In addition to being a homeschool dad and a Reformed Baptist Christian, I am also a Systems Engineer. In my "day job" I have been stumped on an issue since last week, and found the answer this morning.
I was trying to install Visual Studio 2008 on a machine that I inherited when I got this job. Yet everytime I tried the install, it would fail with an error message about not being able to install the Microsoft Document Explorer.
This morning I found a solution that got me past that roadblock. There is a file called rgstrtn.lck that is located in the following directory:
C:\Documents and Settings\All Users\Application Data\Microsoft Help\
In my case the file was zero bytes and it had a date time stamp of June 2008 (before I started working here). After deleting that file and rebooting I was able to progress.
Now on to the next issue...a digital signature problem... Computer programming is just one challenge after another. It's a big puzzle. It's up to programmers to find the solution.
