Cont1.cab is not digitally signed

Recommended Posts

Hi Guys,

I'm getting this error when installed the Content on V4.4, is there any fix for it? Stating the cabinet file is not digitally signed. Indicates the file may be corrupt?

Redownload it if you believe it's corrupted. But lack of digital signing does not necessarily indicate corruption. You can check for corruption by using any of a number of free applications to generate an MD5# checksum for the file, and seeing if this tallies with a known valid MD5# for file. I didn't bother with v4.4 content this time so I can't provide you with a hash, sorry.

You don't happen to have another Content file in your downloads section from the last install do you?


Had the same error pop up, and it was because i had the file from V4.3 still in my downloads folder.


As soon as i deleted that, the error disappeared.
