Quickbooks 2010 on Windows 7 Locking Up

Had a computer come in with Windows 7 and Quickbooks 2010. Quickbooks would look up every time you tried to connect to the bank to import transactions. The strange part was the customer had an identical computer running the same version of Quickbooks connecting without an issue. Turns out the computer had updated to IE9 the month and Quickbooks 2010 was not playing well with the new version of IE.

Error 1402 Could not open key UNKNOWN\Components

If you ever get "Error 1402 Could not open key UNKNOWN\Components\... trying to install a program the solution is fairly simple once you know where to go. The issue is that the permissions on certain registry keys are missing and trying to search for them is useless do to the lack of permission. The location however is as follows:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Components

Note: the S-1-5-18 maybe a different set n here you will find the the key and sub key listed in the error after Components. On these keys you will have to take Ownership and grant Administrators full permissions. The order of those two steps may be reversed. After repairing the permissions the program should install without an issue.

Slow Epson Print Screen

Just had a computer that took forever to load the print screen when an Epson Workforce 610 was set as default. If any other print was the default the screen would come right up but take forever to switch to the Epson in the drop-down box. The solution appears to be common to a variety of Epson printers and is to remove the following file: "C:\ProgramData\EPSON\PRINTER\EPAUDSO1.AUD". The next time you hit print it will still be a bit slow as the file is recreated but after that the print screen will come right up.
