Hi
Note: it happens only at my dev machine
A while ago I was playing with QLMLicense and ISLicense50 dlls to be able use them from a VBA application. Later on I realized I don't need the IsLicense50.dll at all but for some reason I forgot about it and just today when I installed my application on my dev machine (which I normally don't do) and run MS Word with my add-in installed Word is crashing.
From Windows Event log I got this

Faulting application name: WINWORD.EXE, version: 14.0.7153.5002, time stamp: 0x559d6727
Faulting module name: IsLicense50.dll, version: 9.3.3.0, time stamp: 0x53e78912
Exception code: 0xc0000005
Fault offset: 0x0006f6c4
Faulting process id: 0x1d18
Faulting application start time: 0x01d0cb0bdd261e94
Faulting application path: C:\Program Files (x86)\Microsoft Office\Office14\WINWORD.EXE
Faulting module path: C:\ProgramData\KwikDocs\IsLicense50.dll

I then tried unregister the IsLicense50.dll from the path mentioned at the log but the command failed
RegAsm : error RA0000 : Unable to locate input assembly 'C:\ProgramData\KwikDocs\IsLicense50.dll' or one of its dependencies.

I tried
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\regasm.exe /
unregister "C:\ProgramData\KwikDocs\IsLicense50.dll"
as well as

C:\Windows\Microsoft.NET\Framework\v4.0.30319\regasm.exe /un
register "C:\ProgramData\KwikDocs\IsLicense50.dll"

IS there anything what I'm missing there?

  Hi Premysl

  With an Outlook add-in, you need to use the QlmLicenseLib.dll that has an embedded version of IsLicense50.dll. This version can be found in the redistrib.net 4.0\QlmLicenseLibEmb folder.

  You do not need to unregister or register IsLicense50.dll.
  You do however need to register QlmLicenseLib.dll. Please check the article below for instructions on registering QlmLicenseLib.dll.

  Probably worthy to mention that at that time when I used/tested IsLicense50, I used QLMLicense for NetFramework v2.0 but now I use version for NetFramework v4.0
