Hello! I am having problems similar to those described by another member, so any possible solutions may be able to help him/her as well. I am running Windows XP Home Edition with SP2, I have McAfee AntiVirus/Firewall, etc. but it was turned off as per the instructions of the download/install. I had SonicStage 3.4 with Connect installed on my computer, but when I would open it the Windows Installer window would flash on and off basically constantly while SonicStage was "busy" completing any commands. After getting annoyed by this, I backed up the music I had and tried to uninstall the whole SonicStage package (including OpenMG Module and Limited Patch). The latter two uninstalled fine, but SonicStage did not. When I click on the "remove" button on the Add/Remove Programs list, a window pops up for a fraction of a second but disappears. I have also tried booting in Safe Mode, in which case I couldn't even remove the OpenMG module from the Add/Remove Programs list, as "the Windows Installer function cannot be accessed" (b/c of Safe Mode), and SonicStage still behaved the same way. I was told by Sony Support to erase Temp/Internet Temp files, disable startup drivers/devices via running "msconfig," but the ultimate result is the same--installation terminated. I CAN install the Limited Patch and OpenMG Module, but the installation seems to "skip" the installation of the SonicStage.exe, then tells me that the intended application for the "SonicStage Add-on" cannot be found. And after it successfully installs the OpenMG Module, Limited Patch, etc., and it seems like the installation is going okay, an error message pops up, saying: "The installation process for SonicStage 3.4 has been terminated (2051, 20697)." In addition, I wanted to share with you the content of a sonicstage install.log file I found. It read: [5-2-2006 11:07:46] OnBegin() [5-2-2006 11:07:46] OnFirstUIBefore() [5-2-2006 11:07:46] #### OnAbort #### [5-2-2006 11:07:46] - Setup terminate !! Sorry for the lengthy post, but I am desperate for a solution to this problem. Hopefully someone can help me out. hokutonoken
