[wix-users] question for Bootstrapper (burn)

[Steve Ogilvie]

Hi all,

I am using WiX 3.11.1

I have a Bootstrapper which is checking to see if a “parent” installer is installed (will be a certain version and up, to check)

So I am using a check for .NET and my parent product:

<?define MyProductVersion = 2.10.119.0 ?>
<?define NetFx452MinRelease = 379893 ?>

<util:ProductSearch Id="ISMYPRODUCTINSTALLED" UpgradeCode="{<the Upgrade GUID of my parent Product>}" Result="version" Variable="ISMYPRODUCTINSTALLED" />
<util:RegistrySearchRef Id="NETFRAMEWORK45"/>

<!-- .NET 4.52 checks-->
<bal:Condition Message="Wrong version of .NET is installed.">
    NETFRAMEWORK45 >= $(var.NetFx452MinRelease)
</bal:Condition>

<bal:Condition Message="You need to install MyProduct before proceeding with this installation.">
    ISMYPRODUCTINSTALLED >= $(var.MyProductVersion)
</bal:Condition>

.Net works like a charm, the check for my product fails…

It reports:
Setting version variable 'ISMYPRODUCTINSTALLED ' to value '2.10.119.0'
Detected related package: {<the Upgrade GUID of my parent Product >}, scope: PerMachine, version: 2.10.119.0, language: 0 operation: MajorUpgrade
Error 0x8007000d: Failed to parse condition "ISMYPRODUCTINSTALLED >= 2.10.119.0". Unexpected character at position 30.
Error 0x8007000d: Failed to read next symbol.
Error 0x8007000d: Failed to parse value.

Error 0x8007000d: Failed to parse boolean-term.

Error 0. Failed to parse condition ISMYPRODUCTINSTALLED >= 2.10.119.0. Unexpected symbol at position (null)
Error 0x8007000d: Failed to evaluate condition.

If I change the version to check to:
<?define MyProductVersion = 34209911 ?>

Which is the hex number in the registry:

I get:

Setting version variable 'ISMYPRODUCTINSTALLED ' to value '2.10.119.0'
Detected related package: {<the Upgrade GUID of my parent Product >}, scope: PerMachine, version: 2.10.119.0, language: 0 operation: MajorUpgrade
Condition 'ISMYPRODUCTINSTALLED >= 34209911' evaluates to false.
You need to install MyProduct before proceeding with this installation.
Error 0x81f40001: Bundle condition evaluated to false: ISMYPRODUCTINSTALLED >= 34209911

The product is installed, version 2.10.199.0 (in HKLM\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\GUID
Version REG_DWORD 0x020a0077 (34209911)
DisplayVersion is 2.10.199.0

Sigh, any idea what I can do to get this working?

Much thanks,

Steve
