instalation problems

Post by philippe van reeth » Tue Oct 29, 2013 10:02 am

I have following problem during installation of PicoScope6 on my XP SP3.
"A file that is required cannot be installed because the cabinet file E:\software\windows\32bit\...\ has an invalid digital signature. this may indicate that the cabinet file is corrupt. Error 266 was returned by WinVerifyTrust."
What to do with it?
I installed the same program on a windows 7 without any problem.

Hi Philippe,

This is something to do with driver verification on Windows XP.

Is your PC connected to the Internet during installation?

You can also download the standalone executable from

In step 1, select your product and in step 2, select the version of PicoScope 6 you require.

Hope this helps.
