HI,

LexActivator is compiled using VS 2010, so VS 2010 runtime (msvcp100.dll, msvcr100.dll) should be present. Ideally you should ship the runtime with your app as it may not be present in your customer’s OS.

To get the runtime dlls you can download them from micrososft’s website or search for them in Windows 7, and make sure they are in same directory as your exe and lexactivator.dll

Okay I copied both of above DLL from “Windows/System32” folder of windows 7/64 bit system to 32bit vista and getting below exception. This looks like 32/64 bit issue but I can’t find any other dll on my system. Any advise?

You can’t mix the dlls. If your app uses 32 bit LexActivator.dll then you have to ship 32 bit VS 2010 runtime with your app.

You can download the 32 bit runtime from Microsoft’s website.

Well my app is x86 compiled and will look into x86 compiles binaries then. Do you have direct MS link ?

The dll’s have been mailed to your email address.

That worked, Thanks so much!! I would suggest to make a note on help section or API section on your website to easily help user about it. I tried looking over pages but can’t find anything then had to come to forum.
