DLL call needs a full access windows account

[Fluxie]

I hope someone can assist me with the folowing problem:

In the NSIS installer script I created is a license key check which uses a dll in the NSIS plugins folder to check validation.

The problem i have is that if you use a "Limited access" windows user account, he always returns a "INVALID LICENSE" warning, while this is not the case with a Administrator account.

The script I use looks like this:

vserial::IsValid "Encryption secret word" "Encryption method" "License key"

Could it be of influence that the DLL I use is compiled as "Debug DLL"? (He keeps giving meaningless errors when trying to release it as a "Release DLL")

Nothing much can't be told without the DLL itself and preferably its source code. You can use the plug-in tester to test it.

I want to thank you for your answer, but I just figured out what caused the failure.

The error message was caused by a registry check I did, apparently the Windows users with limited access can't access the registry keys in the "HKEY Local Machine" folder.
