Hi all -
I am having some trouble using a system property. My current goal is to
make a backup copy of some *.cmd files in the System32 directory because
on installation I will be overwriting them (and then on uninstall I will
be restoring the backups, but I am not there yet).
My current problem is that I get a "Error 1314. The specified path
'[SystemFolder]' is unavailable" error when I run the MSI.
I am just trying to use the CopyFile element to copy the file
usrlogon.cmd to my install dir. Some questions:
1. It seems I can refer to a system property such as ProgramFilesFolder
in an Id without enclosing it in braces. How is this the case?
2. When I run the msi that the following XML creates, I get "Error 1314.
The specified path '[SystemFolder]' is unavailable" in the log. Is the
property getting defined at a time when I cannot refer to system
properties?
3. When and where can I refer to things like ProgramFilesFolder and
SystemFolder? When should I enclose in braces and when should I not?
4. You can see below that I attempted to define a property with a value
of [SystemFolder]. That didn't work. However, neither did putting
SystemFolder or [SystemFolder] in any of the places that I wanted that
value (such as SourceDirectory in the CopyFile element). Why is this?
<?xml blah><Wix blah><Product blah><Package blah /><Media blah />
<Property Id='DiskPrompt' blah />
<Property Id="SysFolder" Value ='[SystemFolder]' />
<Directory Id='ProgramFilesFolder' Name='PFiles'>
<Directory Id='MinuteClinic' Name='MCDir' LongName='MinuteClinic
Folder Long Name'>
<Directory Id='INSTALLDIR' Name='SLDir' LongName='Server Logon
Folder Long Name'>
<Component Id='BackupCmds'
Guid='A004C7F0-0585-4728-9F3C-C2C402549D7A'>
<CopyFile Id="CopyUsr" Delete="no"
SourceProperty='SysFolder'
SourceName="usrlogon.cmd"
DestinationDirectory="INSTALLDIR"
DestinationName="usrlogon.bak" DestinationLongName="usrlogon.cmd.bak"/>
</Component></Directory></Directory></Directory>
<Feature Id='Complete' Level='1'>
<ComponentRef Id='BackupCmds' />
</Feature> </Product></Wix>
Many thanks to all who respond!
