App Update / Installation problems

[CmHall9]

Is anyone having this problem?
You add or update an app and after it downloads you get ?Update Unsuccessful? or ?Install Unsuccessful" message.
Even after doing some research I figured out how to get around the problem but it continues to persist.
Any thoughts on how to permanently fix this problem?

My work-a-rounds...

If you are getting an "Update Unsuccessful" message...
Some apps like "Android System Info" and "Apps2SD" have a feature that let you move apps to the SD card. Sometimes a portion of an App would actually remain on the phone causing the update error. Move the app off the SD card and back onto the phone and try updating again.

If you are getting an "Install Unsuccessful" message...
I'm not sure what causes this error. However if you go into your "settings/SD card & phone storage" and unmount the SD card you should be able to download and install the app that?s giving you trouble. After your done mount your SD card. You may want to also restart your phone.

I finally found someone who has had some experience with my problem. A Verizon rep said that the two virus scanner apps on my Droid X were causing problems with some apps as they tried to install/update. The virus protection apps were also preventing my phone OS from upgrading. After removing "Lookout" and "Watchdog" my droid was able to download and install OS 4.5 and I no longer have any problems installing or upgrading my apps.

The Verizon rep told me virus protection and malware apps are unnecessary. Google is constantly changing the OS in order to stay head of any problems. He says he rarely ever hears of infected phones.
