At Amitec everyone of us are now using Windows 7. Most of us use the 64 bit version, some are on the 32 bit.
Haven't really had any major issues, just make sure you install the correct versions of PI SDKs, PI OLEDB providers, etc.
Speaking for myself, I have the latest PI SDK, PI OLEDB Provider, ProcBook 18.104.22.168 and DataLink 22.214.171.124 installed. No problems!
Terry VermeerThe reason is, Manual Logger is the only product that released after Microsoft Windows 7 (for which general availability was 22-Oct-09): version 126.96.36.199 of PI Manual Logger released on 09-Nov-2009, whereas PI ProcessBook 3.2 was released on 16-Sep-2009 and PI DataLink 188.8.131.52, 14-May-2009. With that said, I run these on Windows 7 with no problem...
The only manual that actually listed Windows 7 in the OS list was the Manual Logger manual
As for the AF Client v1.3 and Sigmafine, these were released quite some time ago - well before Windows 7 was available. These are not provided nor supported on vCampus and therefore I invite you to contact our regular Technical Support team.
Even for PI ProcessBook and PI DataLink, regular tech support is a better resource than vCampus (which focuses on the programming and integration aspects): they have tools to look up the database for occurences of problems with Windows 7.
