ImApp: An invalid argument was encountered.

Postby Narah » Wed Aug 14, 2013 4:55 am

Your IncrediMail Version: Incredimail 2.0
Your Internet Browser Type: Google Chrome
Your Operation System: Windows Vista

What have you done before the problem occurred?
Installed Incredimail.

If you receive any error message, please quote it precisely:
An invalid argument was encountered.

Please provide a full description of the problem:
I have installed Incredimail on a couple of different computers and never encountered any problems. But this time, after installing, ImApp began showing this small pop-up screen every time I start the computer. It just says "An invallid argument was encountered". When I click "OK", it just goes away without causing any further issues.

I found more people complaining about this on different websites throughout the internet, but I didn't find any real solution or explanation... There should be a reason for these errors to pop up, and I want to know what...

I'd like you to download the full setup file for IncrediMail and see if that solves the problem.

Please click the following link to download and install IncrediMail: ... &beta=true

Please let me know if the problem persists.
