I was able to successfully associate a file type with a specific application using the ftype command. Here is an example: ftype SQL.document="M:\Program Files\Teradata SQL Assistant 7.0\queryman.exe" %1 I created a batch file using this command to deploy across my Citrix farm. -- Susan Martin From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Minero, Hector B CIV NSWCDD, K55 Sent: Wednesday, October 10, 2007 1:02 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] File Associations Hi all, I am trying to associate *.gif files with Internet Explorer for all users. If I modify giffile entry in the HKCR registry,it does not apply to all users. How am I suppose to make this a global change. Change user /install and change the file assoc. in Windows Explorer?
