I have tried all three mirrors for 32bit Windows 10 and it won't install. message is that it is corrupt or invalid. How do I fix this or is it your problem?

Same here, it appears to be a problem with the signature of the package rather than a file corruption

Yup, signature is invalid

I am still getting an invalid signature with 2.34-1 on both 32 and 64 bit windows versions

Installed for me no problem on Windows XP, 7, and 8.1.  I also have a friend that says it installed OK on a Windows 10 64-bit machine, with a valid signature.

I can right-click the installer file, select properties, and it comes up with a valid signature, no problems there.

Maybe this is a weird Windows-10 issue.

Just downloaded the Last version V2.34 64Bit And install works fine. had no issues installing the new version on windows 10

Win 10 is stricter on signature compliance than 8, but that should not be an issue

Just installed 2.34 version and so far it's everything OK. W10 x64.

Oh, it does install, but the signature is still invalid, which is pretty funny for people who waffle on about "security". Anyone using a download tool that checks the vilidity of the download, such as the edge browser or one of the download managers, will see the download as corrupt or damaged.
