Frequently asked questions

Harshal Oza Toolkit & License is independent third-party software: a set of professional tools for supported Siemens NX installations, and the Windows application that licenses, activates, backs up and transfers them. It is built by Harshal Oza and is not a Siemens product.

No. Harshal Oza Toolkit & License is independently developed third-party software. It is not affiliated with, endorsed by, sponsored by, or otherwise connected to Siemens Digital Industries Software. Siemens and NX are trademarks of Siemens AG or its affiliates and are mentioned only to describe compatibility. Siemens NX itself must be licensed separately from Siemens.

It depends on the tool. RenameCAMops, Material Size BOM and NX Backup and Restore work with any NX version. The NX 12 Classic Toolbar and Sheet Up Sheet are built for NX 12.0 only. If you need a particular tool on another version, please ask before purchasing.

Five: NX Backup and Restore, the NX 12 Classic Toolbar, RenameCAMops, Material Size BOM and Sheet Up Sheet. They are on the Install Tools page of the Windows application, which detects your NX installations, checks compatibility and puts each tool where NX will load it. Windows asks for administrator rights and NX must be closed while a tool is installed. NX Backup and Restore is free and needs no licence. Cavity Mill Mixed Cutting and the Post Processor appear as Coming Soon in the application, and NX Role Install is announced but not yet listed there.

Windows 10 or Windows 11, 64-bit, and a supported Siemens NX installation. The application ships self-contained, so no separate .NET runtime is needed. The installer requires administrator rights.

Go to the Download page and click Download for Windows. The installer comes from our official release channel on GitHub, and the page shows the current version. It needs Windows 10 or 11, 64-bit, and administrator rights to install.

After paying on this website, click Download License Key on the success screen to save HARSHAL_OZA_LICENSE.key. In the application, open Backup & Restore, choose Restore Subscription and select that file; the license is installed on this computer. If the file will not download, the success screen can show the key, which you can paste into the application’s Activation page instead. If you bought from inside the application, activation is automatic.

Every computer has a Machine ID, which the application shows on its Dashboard. When you buy, the license is issued for that Machine ID, and it only activates on that computer. To use it on a different computer, transfer it from inside the application; the expiry date moves with it.

Every licence is issued for one specific computer. The Machine ID identifies that computer, and the licence server builds your key around it. Buying on the website therefore needs the Machine ID from the copy of the application you intend to activate — install the application first, and copy the ID from the Dashboard.

Yes, for paid licences. Open Transfer License in the application. The transfer releases the licence from the current computer and lets you activate it on the new one, keeping the same expiry date. Save a backup .key file before transferring, as the application asks you to. There is a limit on how many transfers a licence allows, and the application shows how many you have left. Free trial licences cannot be transferred.

Once activated, the NX tools read your licence from your own computer and keep working without an internet connection. A connection is needed only to buy a licence, to restore or transfer one, and to check for application updates.

The licensed tools stop working once the expiry date passes. Buy a new licence for the same Machine ID to continue. If a licence is extended on our side, open the application and press Refresh to collect the new expiry date — changes are not pushed to your computer automatically.

Yes. Keep the HARSHAL_OZA_LICENSE.key file you downloaded after paying, or one saved from Backup & Restore. In the application, open Backup & Restore, choose Restore Subscription and select the file. Reinstalling Windows can change your Machine ID; if it has, the application offers to transfer the license to this computer instead, keeping the same expiry date. If you have no file, contact support with your payment reference.

The application checks the official release channel on start-up. When a newer version is published it downloads the installer, verifies it against the published SHA-256 hash and installs it only if the hash matches. Some releases are mandatory and are applied before the application continues. Updating never alters your licence.

You choose a duration, and the licence server creates a Razorpay payment link priced from its own catalogue. You pay on Razorpay’s secure page by UPI, card or the other methods Razorpay offers. No payment details are entered on this website. Once Razorpay confirms the payment, the licence server issues your key.

The licence server confirms the payment with Razorpay directly, then generates your license. The success screen shows your Machine ID, plan and expiry date, and offers Download License Key, Download Windows App and Activation Instructions.

The price shown is read live from the licence server, and the server prices your order again when the payment link is created. If the two ever differ, the amount on the Razorpay payment page is the amount charged. Nothing your browser sends can change what you are charged.

All licences are priced and charged in Indian Rupees (INR). If you pay with a card issued outside India, your own bank performs the currency conversion and may add its own fee; that conversion is between you and your bank, and we neither set nor receive it. Taxes, where they apply, are shown before you pay.

Your payment is recorded on the licence server, not in your browser, so it is not lost. If the purchase page is still open, leave it: it keeps checking and shows your license once the payment is confirmed. Otherwise email support with your payment reference and Machine ID, and we will issue the license from the server record.

Licences are delivered immediately and are tied to your computer, so refunds are limited. Where a licence could not be delivered or activated and we cannot resolve it, we will refund. Please read the Refund & Cancellation Policy in full, and contact support before buying if you are unsure whether the software will work for your setup.

A free trial is currently offered, once per computer, and is started from inside the Windows application rather than from this website. Trial availability and length are set on the licence server and can change. A trial licence cannot be transferred to another computer.

Email us, or use the contact form on this website. Include your Machine ID and, for a payment question, your payment reference — that is almost always enough for us to resolve it on the first reply.

First check that the Machine ID on the application Dashboard matches the one you bought for, since a license only activates on its own computer. Make sure you selected the HARSHAL_OZA_LICENSE.key file from your purchase, and that the license has not expired. If it still fails, email support with your Machine ID, the exact error message and your payment reference.

Each licence covers one computer. For several machines, buy one licence per Machine ID. If you need a larger number, contact us and we will work out the best arrangement.
