Unable to run apps from menu

Hi,

After having to send my laptop to be repaired, I dug out my old PortableApps USB drive so that I can use whatever Windows PC that I have available to me.

I haven|t used my old PortableApps drive for a couple of years or so, but had never experienced any problems with it.

Now however, on the first PC that I plug my drive into, I am unable to launch any of my apps from the start menu. I can access my folders, and files from the PortableApps menu (but the back and several of the "Manage Apps" options also don't work).

The only way to open any of my apps is to go directly to the applications folder and double click on the .exe file (this is of course a slightly long winded method of doing it).

I did think that perhaps something had gone wrong with PortableApps itself, so I did a fresh install with the latest version, with exactly the same results.

Any ideas as to what's going wrong? Does it sound like a problem with PortableApps, or the host computer (if the latter what should I look for?).

Thanks in advance for any help in attempting to fix this.
