  <p>I have Windows SDK V7.1 which contains MsiMsp.exe Version 5.0 and Ocra Version 5.0.</p>
  
  <p>My PCP file has following data.</p>
  
  <p>ImageFamilies Table : Family -> fam1</p>
  
  <p>MsiPatchSequence Table : PatchFamily -> fam1 ; Sequence -> 1.0.0</p>
  
  <p>Properties Table : MinimumRequiredVersion -> 200 and other columsn</p>
  
  <p>TargetImages Table : IgnoreMissingSrcFiles -> 0 and ohter columsns</p>
  
  <p>UpgradedImages Table : Family -> fam1 and other columsn</p>
  
  <p>Generated MSP using MsiMsp.exe and run using msiexec /p.</p>
  
  <p>It runs the instller (patch). After upgrade Add/Remove program confirm the upgraded version 1.0.1 but the problem is that my changes are not reflected when I run my exe. i.e, I have modified to show a MessageBox("This is updated project").</p>
