Applications does not start from a mapped drive

Hello,

some applications will not start but quit with an error message, like “this application cannot start from an UNC path…”. This happens for all applications which have a directory “Launcher” under “App\AppInfo” and I try to start from a mapped share. Here some of them which do not start:

- Audaciy
- Foxit Reader
- Gnu Cash (does not shows an error message, but will not start)
- Irfan View
- NSIS
- Sweet Home 3D

Many other works fine, so I would be glad if this can be fixed (I guess with a newer installer version).

This only happens on Windows 7 computer. With Windows XP the applications above work fine.

I also recognized that the Portable Apps Manager will have a problem with Windows 7 too, because he shows the UNC path instead of the mapped drive (linke in XP) and shows a negative free disk space.

Thanks
Peter

Not designed for use from a mapped drive

PortableApps are designed to be used from local drives, whether external or internal.
While some apps can function from mapped drives, it's really outside of the intended scope of PortableApps. Kind of like using a butter knife as a screwdriver - yeah, it works a lot of the time, but it's really a butter knife.

I made this half-pony, half-monkey monster to please you.

PA.c Platform

Do you mean the PA.c Platform is showing the UNC path? If that is so, then every app will be launched from the UNC path and will not work properly.

Are you absolutely positive you are browsing to L:\ (or whatever your drive is) and running StartPortableApps.exe and NOT browsing to \\server\path and running StartPortableApps.exe?

Sometimes, the impossible can become possible, if you're awesome!

Yes

If that is so, then every app will be launched from the UNC path and will not work properly (with Windows 7 you forgot, because Windows XP is working fine).

I have a short cut to the mapped drive. So you can be quit sure I do not start it from the share directly.

Skip SHortcut

Skip the shortcut, open explorer directly to the drive letter and run StartPortableApps.exe from there. When you do that, does the PA.c Plaform come up properly showing the drive letter at the bottom of its menu?

Ups the short cut of the

Ups Sad the short cut of the Windows 7 computer referred to the UNC path.

The short cut of the Windows XP computer to the drive letter.

I'm really sorry that I have not checked this before.

Now I have changed the short cut and it workes fine with Windows 7 too Smile

Thanks a lot for your time!

Peter

No Problem

I figured it was something simple like that. I hadn't seen that issue before, so it was just a matter of getting to the root of it.

I've used NSIS Portable several times...

Launched it via both mapped drive letter and UNC path. I've never had a problem with it.

You said it only seems to affect apps that have an \app\appinfo\launcher directory. I just checked my PortableApps install on my NAS and in addition to NSIS Portable, ImgBurn Portable and Spybot Portable both have that directory. I've used both of them successfully many, many times, using both UNC paths and mapped drive letters, as recently as yesterday.

The existence of

The existence of \app\appinfo\launcher just shows that these apps use the new launcher (PAL), which has a lot more features than older ones.
As of this, I guess that the old launchers simply did not check whether they were running from a UNC path or not.
So, although they seemed to work, not everything might have worked the way it was supposed to.
