How to make an MSI that simply wraps an EXE file
The problem in the second call to ST_LineFromText() is that you are attempting to pass parameters into it, which isn't possible.


How to programmatically read the properties inside an MSI file?
You have:.
MSI install error: This advertised application will not be installed because it might be unsafe
ST_LineFromText('linestring (0 0,v1.pre 0,v1.pre v1.post,0 v1.post,0 0 )',5) 
The string contains 'v1.pre' which is not a valid number, etc.


Always update files in minor upgrade (how to)
If you need to parameterize your query, you either need to generate the string with those values in place, or you need to use a different method.


Where do I install my shortcuts to if I want to put them in the Vista/7 “Games” Folder in the start menu?
One crude but possible solution is:.
Detecting and suppressing REINSTALLMODE=v switch
ST_LineFromText('linestring (0 0,' || v1.pre || ' 0,' || v1.pre || ' ' ||                 v1.post || ',0 ' || v1.post || ',0 0 )', 5) 
This may not do the job - but illustrates the problem..
