I can't seem to download anything from the App Store. I get this message when I enter my username and password:
There was an error in the App Store. Please try again later. (100)
I have tried many times over three days and the same thing happen. I have quit , restarted, reentered everything.
iMac, Mac OS X (10.7.4)
Try here > Mac App Store: "An unknown error occurred (100)" when purchasing
If that doesn't help, open the Finder. From the Finder menu bar click Go > Go to Folder
Type this exactly as you see it here:
~/Library/Caches/com.apple.appstore/Cache.db
Click Go
Move the Cache.db file to the Trash.
Now here:
~/Library/Preferences/
Click Go
Move these files from the Preferences folder to the Trash.
com.apple.appstore.plist
com.apple.storeagent.pllist
Now here:
~/Library/Cookies
Click Go
Move the com.apple.appstore.plist file from the Cookies folder to the Trash.
Empty the Trash, try the App Store.

Thank you. It worked
I'm glad that helped! 🙂 You're welcome
There was a 'corrupt' apple/appstore.plist that I tossed too.
Good to know 🙂
Didn't work for me.
not working for me....please help
This worked for me as well, good instructions, thank you.
I'm running 10.6.8 on an ageing iMac and followed your suggestions; I couldn't action the Cookie one as that folder only had an eSellerate file in it. After executing these instructions, I made one App Store purchase. When I then tried to get an update, I got the messages (my translations from French):
It's impossible to fullfil your instruction
There's an error in the App Store. Please try later (100)
An unknown error has occurred
The first message displays an 'OK' button, the second 'Cancel' and 'Retry'. Clicking 'Retry' often sends App Store into a loop during which it asks me to login (again). Sometimes the message sequence just repeats.
To explain the translation, my machine runs in English but I live in France. This means that I have to use the French store. Looking in the ~/Library/Caches/com.apple.appstore folder I find that it has files with names such as Categories, Purchases etc. in English and French. It's clear from the times reported that they update separately. A source of the problem perhaps?
Finally I should mention that if I login as another user, say root, the App Store works perfectly. Odd? At least it's a workaround.
It works for me too. Thanks a bunch.
DId not work for me. Can't buy anything. Very frustrating.
