I am working on an HP Pavilion Entertainment laptop for a client. It is running Win 7 64-bit, has 4 GB of RAM, uses Office Professional 2007, and is current on all Windows updates. The client complained that just in the last couple of months, when he starts Word, its spash screen comes up and then nothing further happens.
In trying to isolate the problem I used msconfig to selectively disable startup programs and services. I eventually determined that if the print spooler service is stopped, Word will start up just fine. In fact, while Word is hanging, I can stop the spooler and Word will come out of its hang and start up normally. Another piece of related info: going into Control Panel / Devices and Printers will also hang until the spooler is stopped; then it will resume. Another piece of (maybe) related info: there were two Quicken PDF printers on the system which I tried to remove -- thinking they might be part of the problem -- but they cannot be removed.
