--- Comment #7 from Jelle De Loecker skerit@kipdola.com 2009-12-15 02:26:04 --- There are several mentions of this on the Photoshop CS4 app page itself (Premiere Pro CS4 and Photoshop CS4 use the same installer)
I didn't think I should create a new bug for it since bug 18070 was created for the Photoshop CS4 installer.
I could add the debug results with wine 1.1.16.
Attachment id=25093 (from that bug 18070) is the patch that makes the installer work again on current trunk.
