Paul,
If you use multiple checks without a logical condition, they must all be true,
since AND is the default.
This is not specific to Win7, but to 64-bit Windows in general, since 32-bit
applications are always installed into %ProgramFiles(x86)%.
The correct check for your package is below:
<check type="uninstall" condition="exists" path="McAfee VirusScan Enterprise" />
<check type="logical" condition="or">
<check type="file" condition="versiongreaterorequal"
path="%programfiles%\mcafee\virusscan enterprise\mcupdate.exe"
value="8.7.0.659" />
<check type="file" condition="versiongreaterorequal"
path="%programfiles(x86)%\mcafee\virusscan enterprise\mcupdate.exe"
value="8.7.0.659" />
</check>
As an example, for the following all three checks must return true:
<check type="uninstall" condition="exists" path="McAfee VirusScan Enterprise" />
<check type="registry" condition="exists" path="HKLM\SOFTWARE\MyCheck\TestMe"
value="true" />
<check type="file" condition="versiongreaterorequal"
path="%programfiles(x86)%\mcafee\virusscan enterprise\mcupdate.exe"
value="8.7.0.659" />
Nested checks must be done as below:
<check type="logical" condition="or">
<check type="logical" condition="not">
<check type="file" />
</check>
<check type="registry" />
</check>
