I found a good and fast solution.
Download the trail version of WINer tweak 3.
If you installed it you can delete the samsung PC studio 7.
Normally there are 2 files listed called "Samsung PC studio 7", try both of them, and one of them is the uninstall file of samsung PC studio 7.
After the uninstall you can install the new file of PC studio.
I just got my samsung sgh g810 I picked up the installer disk put it in my
computer only after I had installed it I realised that I had installed my sisters
samsung software (which isn't a symbian) so i tried to install my symbian software
i says remove all other samsung software, fair enough.I went to control panel
add or remove programs and "removed" my sisters software. I went back to the
installer and it still gives me the same response. Please remove all other samsung software.
Is there another way except manually removing samsung files??
This doesn't help you...
but, from day one with the i8910, I built and have used a PC with all the latest XP patches, etc. on, just for the i8910. I've never run into any PC studio issues as a result, except one time I had to remove everything (including all registry entries by hand (my choice, but then I must have some kind of crazy streak)) in order to ensure the smooth reinstall of the latest PC studio software (which in itself is, I AGREE WITH EVERYONE HERE, the most incredible level of beta program, RC at best, released that I have ever used). I must obviously have always bought a relatively mature handset before the i8910. I have concluded that for the i8910 product, Samsung's standards dropped a long way.
