Cause: The visual basic 5 runtime is missing.
To Fix:
For the tiftiff.dll to register, you need to install Visual Basic 5.0: From this LINK - click on “msvbvm50.exe” and download it to your desktop. Once downloaded, right-click on it and select “run as administrator”.
You'll receive a Windows message saying that the program was installed successfully. Just click on the option that says “this program installed correctly” and go to the next step.
Register tiftiff.dll by doing the following:
•Click the start menu in the bottom left corner of your computer screen.
•Type “cmd” in the search area. The cmd.exe will show on the list as the only found file at the top of the search results window (the start menu turns into the search results window).
•Right-click the cmd program and select “run as administrator”
•Type the following: regsvr32 “c:\program files (x86)\photolynx\bin\tiftiff.dll”
•Make sure you include the quotes around the path on this or it will not work.
•You should get a window that comes up and says “tiftiff.dll was successfully registered.”
The following MUST be done exactly, or you will get an error:
Install the Visual Basic file by running as administrator,
Right-click on the cmd.exe and run it as administrator
Type the command correctly in the cmd window. It must be typed exactly as it is here and include the quotes around the path.
Also, VERIFY that you are typing the c: drive, not d: or any other drive
