I noticed the directory name for the application assets does not match the format of the App-V package folder name. For instance, on the App-V content share, an application is in a folder called: DentrixXP.001 In the user's profile the folder is called: 5QLLSTBB.I11-26A7600A-2D70-44E0. For many other applications the first part of the name (up to the dash) matches the folder name on the content share, such as RumbaXP.001 with the profile folder being named RUMBAXP.001-454A917-BC19-4DB9. It seems that the random characters appear for applications that exceed the 8.3 format for the asset directory in the sequence. I don't recall this being the case prior to the version 4.6.1 sequencer.
