Hi Jeff,
I installed InDesign CS5.5 from DVD on a clean / fresh installed iMac (late 2014). There were no previous versions of any Adobe software on this iMac.
After installation I started from inside InDesign the Update Tool and it found several updates. All updates were downloaded and installed successfully exept the update from InDesign CS5.5 v7.5.0 to v7.5.3.
The error message said: "Unable to apply updates" (translated from the German error message)
In the logfile I found the error code U43M1D207 and the error message that downloading the update package failed.
I only want / need the file AdobeInDesign7_5_3_Patch-All.dmg from Adobe or a nice person here in the community.
Regards,
Florian
Thank you for the update, Florian. The error U43M1D207 indicates that the update package is being corrupted during the download process.
I would recommend reviewing the settings for any installed firewall or security software that could be affecting the ability to download the update. You can find more information about error U43M1D207 at Error downloading or updating Adobe Creative Cloud apps .
This error can also occur if you have previously installed newer versions of Adobe applications. Thanks for the confirmation that this was a fresh install of CS5.5 on a clean iMac. Even the use of the migration assistant, if used to transfer applications, can cause this error to occur.
