Publish Print Management with IE 7 installed on MPS 3.0

[casperdacat]

Since installing IE 7.0 on my Citrix servers, I can't open "Print Management" as a published app anymore. The command line for the app is "C:\program files\internet explorer\iexplore.exe" C:\Printers.{2227A280-3AEA-1069-A2DE-08002B30309D}

When launching the published app, I get a warning from "ICA Seamless Host Agent" that Windows Explorer was started in an ICA Seamless session and I get a Citrix session desktop with an error saying "Windows cannot find /idlist,:768:12212,C:\Printers.{2227A280-3AEA-1069-A2DE-08002B30309D}"

I'm using MPS 3.0 on Windows 2003 SP2.

I've tried the second official way to publish Print Management specified by Citrix in

http://support.citrix.com/article/CTX884335

but I get a similar warning.

Any ideas anyone?

Many thanks,
Frederik
