[wix-users] Burn: How to pass RegistrySearch result value to Custom Bootstrapper

[Ghenadie Tanasiev]

Hello,


It is not clear, do you want to check if *OceanSoftDir *exists in
registries, or you actually need to get it's value from the registry, like
installation path ? If so, *Result  *attribute of the* RegistrySearch *
element needs to be changed to *value. *In the <Variable> element do not
use $(var...) but assign a default value, which will be overridden by
the *RegistrySearch
*result, if anything will be found.

an example:

<Variable Name="InstallDirPathExists" Value="0"/>
<util:RegistrySearch Id="InstallDirPathRegSearchExists"

                     Root="HKCU"
Key="SOFTWARE\$(env.APPNAME)"
Value="InstallDirPath"
Result="exists"
Variable="InstallDirPathExists"/>
<Variable Name="InstallDir" Type="string" Value="$(env.APPNAME)"
bal:Overridable="yes"/>
<util:RegistrySearch Id="InstallDirPathRegSearch"
Root="HKCU"
Key="SOFTWARE\$(env.APPNAME)"
Value="InstallDirPath"
Result="value"
After="InstallDirPathRegSearchExists"
Condition="InstallDirPathExists"
Variable="InstallDir"/>

Regards,
Ghenadie
