AcroPDFlib.dll and 64bit

Question

0.00/5 (No votes)

See more:

I have an application that I am converting to work in a 64bit environment, this application was initially written to be 32bit. Unfortunately, AcroPDFlib seems to be throwing a 'Class Not Registered (0X80040154)' Error at me.

This is a dll add-in to 64bit AutoCAD so my app must continue to be 64bit. As I have things set for 'AnyCPU' the same binary still works flawlessly in 32bit AutoCAD.

I have no idea where to go from here so any help would be greatly appreciated.

Thank you,
Jason Self

According to this forum post, this is caused when a 32 bit version of the AcroPDFlib is used. As of the writing of that entry (which was quite a while ago) there wasn't a 64bit version available.

Solution 2

build/compile your code with target platform 'X86' and then try.

Unfortunately that will not work when you are bringing the compiled dll into a 64bit environment.
