Libraries I've tried are mentioned in first post. So if I leave Setpatch command in startup-sequence, machine will throw me software failure window before it goes to workbench screen, in other words I cannot get in WB without disabling setpatch command. To be exact, I get "software failure program failed (error #8000000B) C:AddDataTypes". Sometimes I got in WB and got error message while starting some other application, for example error #80000004.. Very confusing. Can this be related to bad RAM or CF card somehow? But to think of it, it worked fine with 3.1..
