I checked for Portable Apps updates today. The updater reported that there was an update for PortableApps Platform 14.2 and it's 4MB in size.
Fine. Update it. I have never had problems with this Portable App in the past.
The updater downloads and then automatically starts the installation process.
It is just a matter of seconds and then I get this error:
Window Title: NSIS Error
Window Text: (X) Error launching installer
If it matters, I do not run my Windows 7 x64 laptop using a login with "administrator" level access. The standard login I use is that of a "user", as defined by Windows 7.
The error can currently be repeated "at will" just by running the updater and trying again and again.

This is an error within NSIS itself that is apparently most often caused by corruption in the downloaded installer or incorrect permissions set on the machine's TEMP directory.
I'd suggest clearing your browser's cache (as well as IE's cache) and downloading a fresh copy via the Download link up to and then running that installer directly. You can select your existing installation to upgrade by pointing it at the directory that contains Start.exe in your current install if it doesn't detect it automatically.
Sometimes, the impossible can become possible, if you're awesome!
I tried again today to use the updater in the PA Menu. Same error.
Rebooted the computer after closing Firefox and some Windows Updates that needed a reboot. Tried again after reboot. Same error.
Gave the Windows TEMP and TMP folder "full access" in the Security Privileges of "Users" in Folder->Properties->Security. Tried again. Same error.
Downloaded the PortableApps menu from your website's download link. Locally executed the installer. Pointed it to the "custom location" of my existing installation (my download was not in the same folder as the Portable Apps stuff). Success.
So based on John's message above along with my own testing, corruption during the download process when using the updater element of the PortableApps Menu is the suspect in this "crime". I wonder if adding a checksum or signature to these downloads along with the appropriate processing code in the PA Menu Updater to check for corruption is a reasonable, but time consuming, program upgrade for the PA Menu.
That's the thing, the updater already verifies the MD5 of the downloaded file. Plus the updater has a built-in CRC check. And it's digitally signed. The suggestions I gave above are the standard NSIS suggestions. 76,000 people have updated to 14.2 by the platform's updater thusfar and yours is the only complaint. The only thing that changed in the updater from 14.1 vs 14.2 is NSIS switching from 3 Beta 3 to 3 Stable. So, it stands to reason - at least at the moment - that something specific on your PC was going on. The only other thing I can think of offhand is either a custom TEMP directory with the platform, a software firewall messing about with things, or some sort of OS issue like an infection or failed update.

Yeah. Not the only one. I do run as admin. I'll try the suggestions.
EDIT:
Worked beautifully.
Thanks.
I've tried to upgrade, but the installer halts when it cannot get write access to PortableAppsPlatform.exe. This leaves me with a partly destroyed PortableApps (since icons, etc. have already been deleted). How do I restore? I can't use the PA menu, since any mouseover complains about a missing button icon, I can't invoke the updater outside PortableApps. -Frustrating! I've otherwise been very happy with the platform, and used it for many years, both on Windows and under Vine on Ubuntu.
==Update==
I took the advice posted above: seems to do the trick.
