avisynth installation problem

[kaiser9]

I have installed and uninstalled avisynth sucessfully the first time. However, I am unsucessful on my next try with the error message:

Could not copy avisynth.dll to system directory-Close down all applications that use Avisynth, and sure to have write permission to system directory, and try again.

I have admin rights and there were no other programs running.
I have also ensured that none of the registry keys below is there when I tried installing again but I still get the same error message.
Any help is appreciated.http://forum.doom9.org/images/smilies/thanks-t.gif

I don't have any idea why, but this happened to me a while back and I couldn't get it unstuck for any reason. So I moved avisynth.dll out (not sure if you can in explorer, I used cmd) to c:\ and it was suddenly deleteable. Played with permissions, made sure nothing had a handle to it, rebooted, all kinds of things, only moving it worked.

Moving to Usage.

@foxyshadis
But I don't have avisynth.dll anywhere on my harddisk...so I can't move it around or delete it.

kaiser9,

Exactly the same thing happened to me. When I tried to reinstall avisynth, after uninstalling it, I got the same message as you.

Have you recently installed Microsoft.NET Framework 2.0? This particular program corrupted AVS Edit 1.1.1.1, although at first I thought that the problem lay with avisynth. Hence my reason for uninstalling it.

I have two machines, and fortunately NET Framework 2 was only installed on one of them. I managed to "get" avisynth on the problem machine by copying the avisynth dll from the clean machine to the problematic one, and similarly I copied the avisynth folder, the one that exists in the Program Files, to the corresponding Program Files of the problem machine. Then I ran the avisynth executable and everything now is hunky dory.

Of course if you don't have a second machine, or it's not appropriately set up, this is not a way out for you.

I had the same problem, i installed avisynth on another computer, copied the dll from the other computer system32 to my computer system32 folder and then i was able to install it normally.

I copied the dll from the other computer system32
could you post a good.dll to install avisynth 2.55 somewhere please? I can send you an email address for it.

after installing avisynth so, I need to restore the modified dll for the usage of .netframework2?

[siddharthagandhi]

I had the problem but I kept reinstalling it, and it worked one time. That was after I deleted the Program Files folder for avisynth.

Here is the dll :)

Please install AviSynth 2.5.7 Alpha2 [April 2nd]- DIAG Release! (http://forum.doom9.org/showthread.php?t=109477). The installer in this release has been doctored to give much more diagnostic information on this type of failure.

If you do get a failure please take a screen grab of the message. Also please arrange the 2 windows so they are not overlapping before you snap the screen, all the information in both windows could be relevant.

Thanks in anticipation for your help in resolving this problem.

[maja_ldm]

to neutrogenik --> thank you MUCH, sorry for my retard. malhauresment I need version 2.55
to ianb --> sorry, at the moment I need avisynth 2.55 to run megui... :scared: if you need its screenshots tell me.

[foxyshadis]

Avisynth 2.57 is definitely compatible with megui. I only know of a few plugins that need SetLegacyPlanarAlignment, and one that simply crashes it (mpeg2dec3), which works with 2.56. All of the ones megui uses are compatible with 2.57.

[IanB]

@maja_ldm,

If you want the installer problem resolved, then please run the special 2.57 Alpha 2 installer and report exactly what happens. I cannot fix what I cannot see! Since I put the special diagnostic version up I have had only 1 active response, I am a little disappointed.

You can always re-copy neutrogenik's posted avisynth.dll if you have problems with the 2.57 version, but I would not expect you to have any conflict problems with megui.

[Wilbert]

Since I put the special diagnostic version up I have had only 1 active response, I am a little disappointed.
I saw this problem on another forum too. I think (as was the case there and sometimes here) the only problem is that avisynth.dll is sometimes set on read only, and thus not overwriteable.
