Knud,

Couple of things we neglected to ask you..

Since this fails on only a couple of machines..
  • Hard disk - is it full? How much space available?
  • %TEMP% Files - Do they need to be purged?
  • Internet Explorer Cache - many applications, probably not this one, are dependent on the Internet Explorer for processing. But, this may need to be purged...
  • Event Log Entries - Anything stick out for you here?
  • Updates - Do you have the updates from Microsoft? That is http://windowsupdate.microsoft.com .. As an alternative, you can do similar updates from http://www.bigfix.com
HTH,
Kent
