First, clean up your TMP and TEMP directories, and stop all unnecessary programs (via Ctrl-Alt-Del and select); futher, disable your antivirus software for all such experiments.
Next, execute the following steps until success occurs.
1. Going to Control Panel | Add/Remove Programs, select "InCD EasyWrite Reader (Ahead Software)", click Add/Remove, then OK as many times as needed, and write down all error messages, if any. Your error message missed the file name, so it's better to check again. Reboot.
2. Download the latest EasyWriteReader from
www.ahead.de by going to LATEST DOWNLOADS | InCD 3.52.20b and selecting InCD | Utilities, or simply using the link
ftp://ftp.nero.com/EasyWriteReader.exe
Then run EasyWriteReader.exe, and report error messages, if any. If it installs correctly, try removing it as in step 1 above.
3. Open an MS-DOS Prompt window, type "cd c:\windows" (without the quotes) and Enter, then "unmrw.exe /UNINSTALL" and Enter. Report the messages.
4. Navigate to the directory C:\Windows\System\IOSUBSYS in Windows Explorer or an MS-DOS Prompt window, and rename the drivers BsUDFRDR.vxd to BsUDFRDR.vx_, and INCDRM.vxd to INCDRM.vx_. You may also need to clean up the registry, but you may skip it if you don't know how to back up and edit the registry. Alternatively, you may use RegCleaner from
http://www.vtoy.fi/jv16/shtml/regcleaner.shtml
Still, for manual cleanup, click Start | Run, type "regedit" and Enter. Then search (Ctrl-F) for "bsudfrdr" (without the quotes). You will probably find something similar to what I have
[HKEY_LOCAL_MACHINE\Software\Ahead\Nero - Burning Rom\NeroCd95\CallbackTable]
"Stack_E"="BsUDFRDR[3] voltrack[5] CDTSD[6] NEROCD95[8] CDVSD[13] CDVSD[14] CDRBSVSD[15] scsi1hlp[15] INCDRM[16] ESDI_506[22] IOS[31] "
"Stack_F"="BsUDF[2] BsUDFRDR[3] voltrack[5] CDTSD[6] NEROCD95[8] CDVSD[13] CDRBSVSD[15] scsi1hlp[15] INCDRM[16] ntmap[19] IOS[31] "
where E refers to my DVD-ROM drive, and F refers to my burner's drive (of course, your drive letters may differ). Edit both Stack_ keys to remove BsUDFRDR[3] and INCDRM[16], where again the bracketed numbers may differ. Continuing the search (F3) will end up with
[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\SharedDLLs]
"C:\\WINDOWS\\SYSTEM\\Iosubsys\\bsudfrdr.vxd"=dword:00000001
Delete this entry for bsudfrdr.vxd in the right pane, and reboot.
