Hello
When trying to enter a couple of servers tonight I got a message "integrity check failed"
The servers I tried were not password protected.
Any Ideas?
Thanks

I wiped the program out and did a fresh install. The problem cleared. Controller map is now screwed and has to be re-done but one step closer

Be sure to install latest version of the game, 1.1.1.1

Thanks
The version that was causing the problem is 1.1.1.1
Something must have corrupted during the install.

Hi Hamblue

Did you use the Torrent download? It will check for corrupt files.

I used the download from DCS. The links came in an email when I bought the software.
The problem happened again yesterday.
The software installs fine and works ok on-line. It seem when I use the single player for a period of time, then go back to multi-player the integrity issue happens.
This last time I installed the game on my secondary hard drive to see if it helps. My primary drive is an SSD.

The software will install fine and work fine in SP no matter what version you have. It is when you connect to MP servers that have a different version installed that you get the integrity check message, IIRC. Or something else may be causing it.

If it works fine in SP, it may not be a corrupt download and/or install. However, you may have a different version.

Might be a good idea to post on the official ED forums for a more efficient troubleshoot and advice.

I think I found the problem.
I have a program called System Mechanic that cleans up the system including registry, clutter etc.
I was running fine all yesterday in multi player. This morning I ran the System Mechanic. Now I get the error.

After about 7 re-installs I isolated the problem further.

In system mechanic you can do a quick analysis or deep analysis of the system. Doing the quick method does not create the problem.
In Deep analysis the program the program identifies 41 meg of clutter. The clutter is in temporary windows files left over from program installation. If you tell it to delete the temporary windows files the result is integrity check fault in multi-player. Single player is not affected.

So it looks like the program is including at least one temp file in the integrity check.
