Avisynth won't install

[ricoman]

I have tried over and over again to install avisynth. It downloads but when I go to install, it starts then stops and gives me a message: You must have administrator rights to install Avisyth!\r\n\r\n(Could not write to registry).
I do have adminitrator rights, never had a problem before. Windows firewall is off. What is the problem? Any ideas.

Yes, the problem seems to be with an AVISynth 2.5 directory being on the drive. Delete this directory and it should install (just remember to save your \PLUGINS directory somewhere first).

Or, do what I did, and install 2.54, then install the latest.

Avisyth 2.54 installed OK, but newer versions still give me the administrator rights message. Tried Rebuilder with Avi 2.5 but now get this message when I go to Encode:
Avisynth open failure: Script error: There is no function named "Mpeg to source" (G:\VIDEOTEMP\D2VAVS\V01000000001001.avs, line5)
Any ideas, or do you know of a troubleshooting guide?

There's something wrong with the command in line 5 of your avs.
Post the script and we should be able to spot what's wrong.

This is the first time I'm trying Rebuilder and Avisynth, so please bear with me. Thanks. Where would I find this avs file line 5? This is what I get when I open the file V01000000001001.avs:
#------------------
# AVS File Created by DVD Rebuilder
# VOBID:01, CELLID:01
#------------------
mpeg2source("G:\VIDEO TEMP\D2VAVS\V01.D2V")
trim(0,4394)
ConvertToYV12()

You did good. The script is the text that's in the avs file.

If I recall correctly mpeg2source requires a plugin, and it looks like your updated AviSynth can't find it. So you either have to make sure the plugin is in the correct location, or you have to expressly call the plugin. I don't use Rebuilder but it appears that Rebuilder assumes the plugin is in the correct location (which makes sense since it wouldn't know how to find elsewhere).
I'm drawing a blank right now on where the plugins need to be, I think it's
"C:\Program Files\AviSynth\Plugins"
but I could be wrong. Maybe someone else can improve my memory.

Putting my plugins into "\PROGRAM FILES\AVISYNTH 2.5\PLUGINS" doesn't work for me anymore. I have to use the LOADPLUGIN command for each one of them. You probably have to do the same.
