SetupAPI fails to find pscript5.dll on Vista 64Bit

[Guest Markus]

Hello,

 

I am installing a PostScript Printer Driver (pscript5.dll + .ppd) using a

custom inf file.

It should install on all current operating systems (Windows 2000, XP, 2003

Server, Vista) and as well on x86 and x64 Systems.

 

I use the Setup API to install it from a windows installer package.

 

It installs well on x86 Windows without prompting for files.

But when I install on x64 Windows (32 Bit install program), it fails to find

pscript5.dll.

 

Even if i add C:\WINDOWS\SYSTEM32\SPOOL\DRIVERS\X64 to the source list

programmatically (using SetupAddToSourceList), it will come up with a prompt

asking me for it's location. If I select

C:\WINDOWS\SYSTEM32\SPOOL\DRIVERS\X64 (which is already in the list), it

will install.

 

Driver installs well (on x64 and x86) when it is installed manually using

the Add Printer Wizard.

 

Has anyone an idea how to fix that weird behavior?

 

Nice regards,

Markus

Markus:

I am not an expert in these issues but it could just happen that the 32-bit

installer is redirected by Vista x64 to

"C:\Windows\SysWOW64\spool\drivers\x64\" instead of

"C:\Windows\System32\spool\drivers\x64\"
