When Photoshop and The Panorama Factory are installed on the same
computer, it may be impossible to open some folders that contain Panorama
Factory projects with Windows Explorer.
As Windows tries to open the folder, it will begin to show the files
included in the project as well as the project file but partway into the
folder it will display an error message that says
"The instruction at "0x77f585c0"
referenced memory at "0x00780069".
The memory could not be written.
The second number is different every time. Windows Explorer then shuts
down and restarts. In extreme cases, it may be impossible to access the
project file to open it within The Panorama Factory itself.
This problem seems to be caused by an interaction between Photoshop and
Explorer. In face, this problem is not really specific to The
Panorama Factory. It can occur on computers with Photoshop
installed, even when The Panorama Factory is not installed.
Fortunately, there are two workarounds for this problem.
I found this problem described in the following web pages:
I was able to confirm that these web pages accurately describe the
problem. That is, the problem seems to be related to three factors:
- Folders containing a large number of image files (like PF
projects!).
- Folders with long names.
- Image file types associated with Photoshop.
Since we can't really change the number of image files stored in a PF
project, we have to workaround the problem by changing the other factors.
There are two workarounds. It seems that you can correct this problem
using either one of the workarounds.
I have confirmed that each of these workarounds corrects the problem. A
third workaround mentioned in the referenced web pages, removing a
Photoshop DLL called psicon.dll, was a little too scary and I did not try
it. I feel that the two workarounds I've listed here are the preferred way
of correcting the problem.
Uninstall Photoshop. Reboot. Reinstall Photoshop and when the installer
asks what files you want to be associated with Photoshop, do not select
the problematic file type(s). In the case of The Panorama Factory, these
are TIFF and BMP. JPG and PNG could also be promblematic if you store them
in the same folder as the project. (By the way, it is not enough to just
change the file associations. You need to uninstall Photoshop and then
reinstall it to correct the problem.).
