Hi Jennifer, Thank you for your update As i understand from the below comment, the MD5 key  has dependency with source path.  But i doubt the same since the source path change is also there in previous installer, but set up size change is minimal. Could you please confirm if the MD5 key generation is dependent on file size, because we see such change only when file size/contents change. The component ID remains the same.   ... View more

Hi, On analyzing the report file generated during build, we observed that  each component has a 'size in library' variable getting added to the setup .exe.   In the issue occurred scenario, value was present for 'size in library'  attribute  for the files replaced when compared with the previous build file. In the previous build file 'size in library' attribute was absent for the added files. So we guess that it is something related to this attribute. Also against each component a MD5 hash is generated.   For the components which have same hash value  size in library' attribute is not getting added in build. Has anybody seen such an issue and how is the MD5 value generated for each file. Is it generated based on file attributes such as size, date etc? ... View more
