"The setup files are corrupted." error when installing 3.1.10.11626

It sounds like you have a corrupt download. Try downloading it again from our website. Sometimes, web-browsers will cache a download it thinks is "done" without redownloading the file. If this is the case, try clearing your cache, trying a different browser, or downloading from an alternate location (like download.com).

(If you are using the built-in auto-updater, that uses IE to process the commands.)

Hello!

I have 3.1.9.11282 installed and it works fine. Now I try to upgrade to 3.1.10.11626 but I get the error:

"The setup files are corrupted. Please obtain a new copy of the program."

Running on Windows 7 Enterprise.

Thanks for help
