If I understood you correctly, you are saying that on a system with a freshly installed XP Pro SP1, the installer of Nero 22.214.171.124 fails while trying to copy msvcrt.dll. This is very strange (I installed Nero 126.96.36.199 on my XP Pro SP1 box without problems).
I presume, of course, that you are logging in as an administrator.
As I wrote earlier, on my XP Pro SP1 box in C:\Windows\System32, I have version 7.0.2600.1106:
08/29/2002 11:41 AM 323,072 msvcrt.dll
However, Nero 188.8.131.52 installed in C:\Program Files\Ahead\Nero version 6.1.8924.0:
10/09/2002 12:38 PM 290,869 msvcrt.dll
Hence it seems that Nero uses its own version of msvrct.dll.
Could you check the error message from the screenshot again? Maybe there is some indication about the copy destination?
I can only guess that the error occurs when Nero tries to copy msvcrt.dll from some temporary directory to its own directory.
Thus apparently your problem has nothing to do with the system msvcrt.dll, and you should leave it alone!
If your software setup is OK (i.e., your OS is clean and no program is interfering with Nero’s installer), consider the following.
First, try to clean up your temporary directories. By observing the installation, you may see where the installer expands its files; e.g., on my box I had
C:\Documents and Settings\KCK\Local Settings\Temp\Nero.tmp
Delete both the Nero.tmp directory and C:\Program Files\Ahead, and try installing Nero again.
If the installation fails, run diagnostics on your hard disk.
Let me add that the usual fix for Nero problems with mscvrt.dll is to download the file
and run it to reinstall msvcrt.dll, but I don’t know which version it installs, and your system version looks fine anyway.
Let us know about your experience.
