It has come to our attention that the WISE install system we use is NOT compatible with the 64-bit version of Windows 7. (Kind of strange, because WISE works fine on Windows XP x64 and Vista x64).
While PMView itself works flawlessly on all 32- and 64-bit flavors of Windows 7, the installer may give you a DLL error and refuse to run on Windows 7 x64.
If you use the upgrade path in Windows 7 that preserves your installed programs, you should have no trouble continuing using PMView. However, if you choose a CLEAN install, you may be unable to run PMView's installer.
We are working on getting a new installer for PMView ASAP. (The new installer will have x64 support and also lets us distribute the native 64-bit version of PMView that has been available since March 2007).
Thanks,
Peter
