A search for “DivX” on my hd found nothing so DivX isn’t installed. The Sony did come w/ video editing & dvd player software installed - dvgate, something called motion jpeg software decoder & intervideo windvd - maybe one of these also uses cdr4_2k.sys. But they aren’t loaded at startup and I haven’t installed/opened/used any since installing WMP 9 so I wouldn’t think any could be causing a blue screen.
The version of cdr4_2k.sys in system32\drivers on the Sony is 184.108.40.206, which appears to be the correct version for wmp9 per the only link I could find re the DRIVER_ULOADED_WITHOUT_CANCELLING_ PENDING_ OPERATIONS - cdr4_2k.sys error http://club.myce.com/f59/blue-screen-cdr4_2k-sys-roxio-245352/.
In its Startup tab WinPatrol has several dll files listed that were supposed to run once at the first startup after installing wmp9 and these dlls are still listed in the registry under HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce. I think either I did not reboot after installing wmp9 before running windows update and installing wmp updates like I intended and thought I did and the updates are preventing wmp to complete its installation or I did reboot but the runonce dlls didn’t run or ran but didn’t clear from the registry for some reason.
I think I should uninstall the recent windows media updates, uninstall wmp9, clear the runonce dlls from the registry and try rebooting.
In the above link I understood the cause of the blue screen to be the replacement of the cdr4_2k.sys in system32\drivers installed by wmp being replaced by a later version when DivX Player 6.5 was installed. I couldn’t figure out exactly what Ascii2 was asking, but rptasiuk suggested reinstalling DirectX device drivers. Would this enable wmp to use a later version of cdr4_2k.sy? How do you install DirectX device drivers?
I’m not familiar w/ windows media/gaming components - don’t know what windows Media Format Runtime is or when DirectX is necessary. No minimum DirectX or other windows component versions were listed in the WMP 9 readme. DirectX 8.1 is installed on the Sony. I was planning on chking if the latest version of DirectX 9 was compatible w/ win2k after I finished installing all the security updates. Per rptasiuk it sounds like I should reinstall DirectX after installing wmp, whether I stay w/ 8.1 or upgrade to 9.
I’m wondering if I get wmp successfully installed if I’m likely to have a problem later with another program installing a later version of cdr4_2k.sys and if I can prevent that by installing DirectX device drivers after I install wmp.
Genie backup software has a Sonic version of cdr4_2k.sys that I guess loads from program files\genie. What would happen if I ran wmp & genie at the same time I don’t know.
