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\...\data1.cab 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.
