I am the sole user of the PC, am part of the Administrators group, and am running Vista SP2. I added CamStudio to my list of apps, and it downloaded and installed correctly. It can be run successfully from the installation.
However, I have tried 3 times to use PortableApps to update it, when it showed that an update was available. Each attempt has failed with the same error. As soon as the download is finished, and installation begins, it stops immediately with the message "Can't initialize plugins directory. Please try again later."
I notice that the PortableApps directory structure does not include a "Plugins" directory. I thought that might be an omission responsible for the error, because the program might be able to install without it, but not update.
What do you think?
