Turn on "Show Hidden Files" option in Windows Explorer Step 4. You will see 3 MSVN_* files now. Step 5. Delete them All. Launch Installshield and it should work. Unfortunately, this didn't work for me at all. After I did it, I no longer got the message "license corrupted", but IS did also no longer offer me the trial (the trial ended immediately). Guess I could activate a paid license but I'm hesitating to spend money on a product that crashed three times in the first hour of using it in the trial... BTW, I found the following message in our event log: Product: InstallShield 2018. The application tried to install a more recent version of the protected Windows file C:\Windows\SysWOW64\dbnmpntw.dll. You may need to update your operating system for this application to work correctly. (Package Version: 2000.85.1022.0, Operating System Protected Version: 6.3.14393.0). That was a short time before or after the crashes.
