A: Yes. ABViewer 15 is fully compatible with Windows 7, 8, 10, and 11 (both 32-bit and 64-bit).
| Problem | Typical Cause | Quick Fix |
|---------|----------------|-----------|
| “Invalid license key” error | Typo, extra spaces, or using a key for a different version | Re‑copy the key directly from the source; ensure you have a 15‑specific key. |
| No internet connection prevents activation | Offline environment or firewall blocking ABViewer servers | Use the offline activation workflow; temporarily allow abviewer.com through the firewall if possible. |
| License not recognized after upgrade | Key tied to an older major version | Contact ABViewer support; they can issue an upgrade‑compatible key or provide a conversion procedure. |
| Application crashes after registration | Corrupted installation files | Re‑run the installer using the Repair option, or uninstall and reinstall fresh. |
Now for the critical part — entering your license key. ABViewer 15 offers two activation methods: online automatic or offline manual.
A: A standard commercial license allows installation on two computers (e.g., work PC and home laptop) as long as you are the sole user. For multiple users, purchase additional licenses or a network license.
Installing your ABViewer 15 license key should take less than two minutes if you follow the official method: download from the vendor, use the .lic file or code, and activate either online or offline.
Resist the temptation to search for "free license keys." The risks—data theft, legal action, and corrupted files—far outweigh any short-term savings. A legitimate license not only protects your computer and your designs but also grants you access to technical support, updates, and peace of mind.
Have a valid key and still facing issues? Contact CADSoftTools support directly via their helpdesk or call your reseller. Do not trust third-party "activation guides" that ask you to disable your antivirus or run unknown executables.

Version Mismatch: Ensure you aren't trying to use a version 14 or 12 key on version 15 software.
Admin Rights: If the key won't "stick," try right-clicking the ABViewer icon and selecting "Run as Administrator" before entering the key.
