To install QuickTime Alternative v1.72 I use this:

REG ADD %KEY%\009 /VE /D "QuickTime Alternative v1.72" /f
REG ADD %KEY%\009 /V 1 /D "%CDROM%\Software\QuickTime\QuickTime.exe /VERYSILENT" /f

During unattended installation I get this error message:

This application has failed to start because MSVCR71.dll was not found. Re-installing the application may fix this.

When the unattended setup finishes, I uninstall and re-install QuickTime Alternative v1.72 and the message does not appear again.

Any ideas what's causing this?

Try to install QTAlt later : it's likely and app that you install updates msvcrt71.dll (Acrobat for example).

Use Quicktime Lite instead, ksphere.free.fr

smaller then Alternative, always worked perfectly here.

or if you use the $OEM$ folders, just find (through google) MSVCP71.DLL and msvcr71.dll and put them in $OEM$\$$\system32

that works for me

It seems that a lot of previously installed software are using that DLL file.

PowerDVD

Nero Burning Rom

Advanced System Optimizer.

Nero and PowerDVD are installed later.

At the end of installation, do you have a msvcrt71.dll file on your computer ? If you do, just move QTAlt at the end. If not, you'll have to put it there.

Also, an app that use a dll may not complain during installation.

i believe that version 1.72 has some problem in the setup routine.

i always installed previous versions without any problems.

there is a newer version, 1.73 but i havent tested it yet. i hope the dll problem is resolved now.

I tested version 1.73 and it's OK

glad to know that the problem is solved in the new release.

thanks nucleus.

Download latest version QuickTime Alternative 1.75 and it does not has this problem.

That was solved 2 versions ago !
