SymptomsAfter upgrading to Parallels Desktop 7 Windows applications crash on start.
CauseThis may happen if icons of Windows applications were moved to a path different from "~/Applications (Parallels)" folder prior to upgrading to Parallels Desktop 7. Parallels Desktop installer is unable to access such moved icons during the upgrade. As a result the outdated icons launch Windows applications with incorrect parameters leading to applications' crash.
Resolution1) Delete those moved Windows Applications icons.
2) Use the correct Windows applications icons, which are now available in "~/Applications(Parallels)" folder.
