Settings page.
See Specifying Patch Removal Settings
Note
Multi-patch Media Settings: During patch creation, entries are made in the Media
table of the patch installation. The following options populate the Media table. For
each subsequent patch, the file sequence start number and the disk ID start number
must be higher than the one in the previous .MSI or patch file. To enter these
numbers accurately, you must have access to the most recent patch file distributed
to end users.
File Sequence Start, Disk ID Start
The file sequence number indicates which files in the File table are located on a
particular source disk. The disk ID number indicates how many media entries
are in the Media table. For patches, these numbers must be at least 1 greater
than the corresponding numbers in the most recent patch or .MSI for this
application installation. To specify these numbers, browse to the most recent
patch file created for this installation.
Volume Label
Enter the name of the CD or other media on which this patch will ship. If the
application needs repair in the future, Windows Installer uses this label to tell
the end user what media to insert to perform the repair. If the patch is not
shipped on any media but is distributed over the Internet, this field is ignored.
Disk Prompt
Enter the prompt that the end user should see if this application needs to be
repaired. Example: Insert the disk labeled Application 2.0.
14. Click Next to begin the patch creation process.
During patch creation, you might see a message stating that the versions between
the target image (previous version) and upgrade image (new version) do not
match. This is normal; click Yes if this message appears.
Note
If the date and time of a file in the upgrade is earlier than the date and time of the
matching file in the original installation, Patch Creation changes the date of the file
in the upgrade file to be later than that of the original installation.
The Compile Patch page notifies you when the patch creation is completed.
15. Click View Log to view a log file of all actions performed by Patchwiz.dll to create the
patch.
If the patch file could not be created, use the log file to determine the source of the
error.
