Hang While "Installing Lightroom Plugins" During Installation

Our Development team is aware of a problem with the Photo Raw 2018 installer hanging at "installing Lightroom plugins" when attempting to install the update to version 2018.1 or 2018.1.1. However, we have a workaround for you! You will be able to install the most current version of the Photo Raw 2018.1.1 by following the steps below.

Please follow these steps carefully as these steps have resolved this problem for all of our customers. 


Unfortunately this problem is impacting a small portion of our Windows users and this problem still exists in the most recent 2018.1.1 install on the ON1 Photo Raw 2018.1 Release Notes Page. However, we are fully committed to resolving this problem in future updates, but in the meantime, we have a special build that will allow you to install the update to version 2018.1.1. 

In order to get past the hang while Installing Lightroom plugins, please download and install from the link below on top of what you already have. You do not need to uninstall prior to installing the 2018.1.1 update from the link below:

ON1 Photo RAW 2018.1.1 Special Build (

Please make sure the download is fully complete prior to launching the installer. If you have multiple downloads of the Photo Raw 2018.exe file in your Downloads folder, please make sure you are installing the latest download. To launch the installer, please right click on the .exe file and choose "Run as the Administrator". 


Please note, since this is a special build ( to fix this problem on a small number of our Windows users, you will notice that your Photo Raw 2018.1.1 build number does not match the build number shown on the Release Notes page mentioned above. This is normal.

This special build ( will fix the "hang while installing Lightroom plugins" and allow you to install the program. This build includes all of the same bug fixes and new features added in the 2018.1.1 build on our Release Notes Page:


After installing the special build from the link above, you may notice that the program is notifying you that an update is available to "build". DO NOT install the update to version 5088, since this version will likely fail for you when "Installing Lightroom Plugins".

If you are prompted to update your version of the Photo Raw 2018.1, simply click the "Skip" button shown below:


This will skip the update to build, and leave you with the build so you con begin editing your photos. Please remember, the special build ( that you have installed from the link above, will fix the "hang while installing Lightroom plugins" and also includes all the same bug fixes and new features in the 2018.1.1 update

Both builds ( and are exactly the same once you get the program installed.
