Avast! for U3

[El Polo]

Hello World! 

Sorry if this post is not in the right category, but I didn't find anywhere to post about U3 version of avast!

So here I am, with my 1GB SanDisk Cruzer USB U3, experimenting trouble using avast! 
Since 1 or 2 weeks ago, when I launch avast!, U3 launchpad gives me an error:
"An error has occured while trying to start the selected program"
So I decided to uninstall and reinstall avast, but:

• when installing, launchpad says "Installation complete" => normally installation is NOT complete before avast! has turned on automatic updates and performed a scan of the key
• when trying on an other PC (at university), avast! installs and runs perfectly, and when I come back home it doesn't run no more

So the problem is in MY computer... but I didn't make any important change last weeks...
I also tried to uninstall all U3 launchpad, format the key, then reinstall it, and the problem is still there...
All my others programs (cruzersync, Filezilla, Winrar, EditPad etc...) work perfectly.

So please give me new ideas... 
Do avast! need any service to run?
What shall I do?

Many Thanks for your help, and sorry for my poor frenglich 

I run on Windows XP Home, well

Yes this will do for the U3 edition as it doesn't have its own dedicated forum.

There have been a few posts that I recall about the U3 version, so a forum search for U3 or launchpad, etc. may return some info.

Searching for informations about my problem, I found a lot of good infos, but nothing about the current $%?&* bug...

Hopefully someone with some experience of the U3 version or one of the Alwil team will pick up on this.

Does the Launchpad's "An error has occured while trying to start the selected program" message come up even before the avast splash screen is displayed?

If so, can you check your TEMP folder..? Is it accessible? Does it have some disk space available?

Thanks

The message appear, and nothing else happen... no splash screen
The avast process just apprear half a second in the task manager and disappear when the message come up
I have more than 400MB free on the key

but I think you've found something... the TEMP folder, in "C:\Documents and Settings\El Polo\Application Data\U3", with contains "cleanup.exe" and "Launchpad removal.exe", is read-only...
I tried to change it, but even when I deselect the attribute and apply changes, it doesn't change...!
it appear normal until I close and reopen the properties window, then it remain read-only

modification:

were you talking about this temp file? I think I misunderstood...
so, I don't know what to do... I can copy/paste here avastu3.ini and setup.ini 

modification2:

I'm sure the problem is somewhere on my PC... I tried booting Windows in Safe mode, the launchpad runs correctly, other u3 programs too, but avast! doesn't :'(
there's a parameter, or something somewhere... could you please indicate me the basic parameters of avast! ? does it use Internet explorer settings? does it use any technology as .net or anything like that?
the error occur in the installation too, avast! always ask to turn on automatic updates and perfrom a scan... before launchpad indicates "installation complete"
but on my PC, it simply indicate "installation complete"
there must be a process during installation that fails, and make all the program fails to launch later...

modification3:
here is a part of the launchpad log file:

[LaunchPad][02/02/2007 00:21:28.218][PID:492][TID:544]: Failed to create the action process for action with command "C:\Documents and Settings\El Polo\Application Data\U3\0000060329031215\1F30627F-0195-44d4-8C24-1999F3C02C50\Exec\AvastU3.exe "C:\Documents and Settings\El Polo\Application Data\U3\0000060329031215\1F30627F-0195-44d4-8C24-1999F3C02C50\Exec\AvastU3.exe""

I found a topic http://forum.avast.com/index.php?PHPSESSID=3272b9ff40c0ab7b45f899ebcd38c956&topic=23154.msg210380
I'm gonna try some of these tricks

=> I tried all tricks, nothing happen...
what is this §%µ¨£$:*¤ u3lang.dll

[El Polo]

 

I tried a trick that worked, but just one time
at university I copied the c:/doc.../app/...u3/.../.../exec folder of avast, which was normal, with lots of files and programs
at home, there is just avu3_upd.exe and AvU3Launcher.exe in this same folder
I pasted all the "normal" exec folder, and ran avu3launcher, and avast ran!!!
but... that was just a temporary trick, next time I've launched avast, the bug came up again...

[El Polo]

...
I'm going to try to stay cool   

does avast! need any external tool? any service, platform, software, update of windows...
is there any avast!U3 developper here???
what is this process that happen during correct installation? (i mean when avast ask for updates and first scan)
what can prevent avast to do that???
avast need something!!! and I don't know what...  :'(

Well, it's important what is on the U3 device itself, the stuff extracted to C: is just temporary.

When you uninstalled and reinstalled avast! (as written in the first post) - did you download a fresh copy of the installer (or did you install it directly from the U3 central) - or did you have a local copy? What I'm asking is what was the exact version you installed

[El Polo]

I tried with all I was able to, with the first package (that was on the key originally), with the lastest version directly on the Sandisk download center, with the lastest version directly on the U3central, the lastest .u3p version on avast! web site, and the lastest .exe version (on avast! web site too)


edit: humm, in English, is the name "USB key" correct ? or is there an other word?

edit2: of course the temp folder on c:/ drive is not important, but the content on my usb drive is exactly the same at home and at university, but it doesn't work at home...

[El Polo]

  so there is no solution?

[El Polo]

some news, but no solution:
I've applied at home exactly the same configuration of services than at university, but no change...

could it be a environment variable problem?
