Hello,
yesterday I have installed IS2015 on VM without license key.
I wanted to test it before I put IS2015 on developer PC.

Today I can not start IS2015 any more.
It comes following error message:

---------------------------
InstallShield
---------------------------
The product license has been corrupted. You must repair the license before you can continue. Click yes to repair now.
---------------------------
Yes No
---------------------------

---------------------------
Repair Complete
Thank you for choosing Flexera Software
------------------------------------------------------

Internet connection is established.

What could I do?
I can not continue my tests.

Step 0. Ensure this is the only PC where the same license of InstallShield is used.
Step 1. Go to %PROGRAMDATA%\Flexera
Step 2. You will see two MSVN_files.
Step 3. 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.
