Hi Angus,
I've updated to the latest version and it compiled and installed okay - as did 8.61
Unfortunately the problem is still there - same errors as before when I drop the X509certs component on the form.
Annoying to say the least, but as I said, I don't have the time to sort it out at the minute.
I'll have to look to another solution and maybe revisit ICS at a later date.
