Because there are a lot of useful docs, links and other useful information about MS AppV (formerly SoftGrid), I tried to help myself and others to keep this stuff a bit together for future use.
SoftgridGuru (nice forum for all kind of questions and answers around AppV)
MS AppV Support KB for searching Error Codes
SFTDownloads (free available App-V packages)
App-V Technet Forum
OSD File explained in detail
