Screengrab.exe needs lpng.dll?

[gsvarney]

Hi,
I am running LanSweeper on a Vista machine. Most things seem to be working fine. However, the screenshot function is not working. If I try to run it from a command prompt on the Vista machine I get an error "this application has failed to start because lpng.dll was not found...." If I launch the screengrab.exe by dbl-clicking it, I get the popup window asking for the computer name. I have located and copied a lpng.dll into the same folder as screengraber.exe, and have also tried it in the Windows\system32 folder. Is this a Vista thing or what? I tried screengrab.exe on my computer with a computer name as an argument and it worked.
Maybe I need to move Lansweeper onto a different machine without Vista...

Thanks,
Geoff

OK, I messed with this some more, cleaned some stuff up and it's working with screengrab.exe in the system32 folder. However, in order to get it to work off my workstation I had to copy screengrab.exe and lstrigger.exe into MY system32 folder. Maybe that's been said, but I misunderstood it was needed on each station that would use the Web interface. I also set IE to autodetect LOCAL INTRANET and that helped in my case, even though the IP was already in trusted sites.

It's all good now!

Thanks,
Geoff

Well, I did that, but still no screenshot showing up or file being created. This wouldn't be a problem with the IIS somehow would it?

best is to copy the screengrab.exe on your computer in a directory found by the searchpath (windows/system32)

As far as I can find "lpng.dll" is an external (non standard windows) library to create png files. (not used by screengrab)
Screengrab created .jpg files instead of .png files

Ahh, forget it! I found some "rogue" copies of "screengrab.exe" which were NOT YOURS that were in a location in the path. It now works from the command line.

However, still not working from the Web interface. I get the error in IE:
Line: 135
Char: 9
Error: The system cannot find the file specified
Code: 0
URL: http://<LS server IP>/default.aspx:item=compdetail&comp=<client name>

I'm running the Web interface on the LS server, which is in the trusted sites in IE.

Have I missed something else?

This error is not reported at the moment.
Do you also get this when you run this from an XP machine?

Actually, when I drag the application over to my XP machine and run it from the command line (with a computer name as an argument) it works.
