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>
