You got two choices. Factory reset the phone and wipe the cache etc. OR install adb boot into recovery and issue this command.

su
rm /mnt/secure/asec/smdl2tmp1.asec

Also check your SD card and delete everything in there. And try the install one more time.

thank you for the help turns out it was the SD card unmounted it and all the apps installed no problems must be something bad on the card.

No need to clear the ROM or reset your phone.

Simply apply this solution to resolve the issue; You need to delete one file: /sdcard/.android_secure/smdl2tmp1.asec. Either put your microSD into a card reader and delete the file or connect your phone to your pc and remove the file. Works like a charm and the error will not return. :)
