Hi,
I'm having some small issues with security on Vista. I am running a Custom
Action before installation to backup any files that already exist, so they
are not lost in the installation. I am using VBS, despite some people's
dislike for it, as I know of no better way.
<!-- Backup Files -->
<Binary Id='Backup.vbs' src='VBS\Backup.vbs'/>
<CustomAction Id='BackupFilesOnInstall' BinaryKey='Backup.vbs'
VBScriptCall='Backup' Return='check' Impersonate='no' />
The script is set as no impersonate to try and run as the system level, so
it has security to do the actions it needs - backup files.
Using Orca, the Type is 2054, which as 0x800 is set, should be running as
the system AFAIK.
In the MSI log, I get this:
MSI (s) (44:C8) [13:06:27:351]: Hello, I'm your 32bit Impersonated custom
action server.
MSI (s) (44:6C) [13:06:29:845]: Product: TestProd 1.2.1.5 -- Error 1720.
There is a problem with this Windows Installer package. A script required
for this install to complete could not be run. Contact your support
personnel or package vendor. Custom action BackupFilesOnInstall script error
-2146828218, Microsoft VBScript runtime error: Permission denied Line 37,
Column 41,
Line 37 is this:
if not (fso.FolderExists(Folder)) then fso.CreateFolder Folder
I.e., creating a backup folder. I have verified that Folder is correct by
MsgBox'ing it (it is like c:\\program files\\myapp\\backup).
So... any ideas why the script cannot create a backup folder?
A big thank you for any suggestions :)
