running pushprinterconnections.exe on any client has popup "not a valid
Win32 application".

running PPC.exe on DC works fine.

I have tried to add printers with vbs, bat, and PPC, nothing has worked,
never any log.

ANy help GREATLY appreciated!!

Are you running an x64 version of pushprinterconnections.exe on the x86
clients? I normally run the x86 binary on x86 and x64 clients which does
work.

if the application runs it will create a log with the -log switch, but I do
not think you are getting that far.

I am not sure how the binary was packaged on x64 R2 server but verify you
have the x86 version.

Alan - YOU THE MAN.

Beat me, whip me, make me write bad checks for not thinking of that.

This is my first x64 Server!

I normally run the file from the DC sysvol share or other network share as a
logon script in the policy so the network will be up for sure to make the
connection . I have seen issue where disabling Fast Logon Optimization is
required to get the printer connections but I have never had to do this when
running the binary from a network share.

I'd specify -log initially to get the ppcuser.log in %temp% for connections
per user or ppcmachine.log in %windir%\temp for connections per machine.

Wn trying to install i also got the error as

x64.exe not a valid Win32 application


And nw i got solution which i put into my blog
