Cumulative patch sets for OpenFlows | Hydraulics and Hydrology products provide fixes to previously reported software problems (known issues). See above for a list of applicable OpenFlows products. As the name implies, these patches are cumulative, including all available "hotfixes" for the respective version (see further below for how to find the list.) These patches are helpful for short-term potentially work-stopping issues so that you do not need to wait for the next full version release. (see note further below) They contain mostly updated .DLL files which automatically replace other .DLL files in the installation folder for a particular OpenFlows product that contained the reported issue.
A "known issue" is a software defect that has been found either by one or more users, or through internal testing, and was deemed important enough to resolve in a patch (rather than waiting for the next release).
Starting in early 2019, patches are delivered with a .MSP (Microsoft Patch) extension. Prior to this, they were executable (.EXE) files. When run, the MSP-based patches will look similar to the original installation wizard, and will prompt you to Update the software, after an automatic initial check to ensure you have the right version installed.
Currently, cumulative patch sets can be requested by contacting Technical Support (Forum / Service Request)
As of 2019, updated versions of the products are released on a quarterly basis, which include patches/fixes, plus more. To check for such updates, open the CONNECTION Client (a small application that runs in your System tray when using Bentley products) and check the "Applications" section for updates. If an update is available and you have the permission to do so, you can install the update from the CONNECTION Client.
Between these version releases, fixes for potentially work-stopping issues are delivered as a "hotfix" cumulative patch set for the existing production version, and you will need to contact Technical Support to receive it (if you cannot wait for the next release.)

Currently, the cumulative patch sets replace individual patched files (mostly .DLL files) in the product’s installation folder for issues reported by users for that particular version of the product. This is different from Bentley products that use “priority builds” - a full installation file that includes the patched issue, with a new build number. There is value in uniquely identifying patched versions (especially when managing large deployments, where it is important for all users to be on the same "update") but there is also value in the ease-of use for patch sets (quicker installation, no compatibility concerns). As a compromise, current patch sets will update the date seen in the product’s “About <product name>” window to show the date of the patch that was created. This way, a user can check if they have a patch (and if other colleagues in their company have are on the same patch) by looking at this date.
If you have applied a cumulative patch set and do not see the updated date, you might be using a patch that was either from before the dates were updated, or it was accidently missing the component to update the date. To confirm the patch date in these cases, navigate to the product installation folder, sort by modified date and look at the date of the "Patchlog" text file that should appear as the most recently modified file.
A list of the known issues and their fixes is included in a patch log text file. Currently, after patching, this can be found in the product’s installation folder, "C:\Program Files (x86)\Bentley\<product name>" on a 64-bit computer and "C:\Program Files\Bentley\<product name>" on a 32-bit computer. The file is a text file named "PatchLog.txt".
Yes - all known issues resolved in a particular cumulative patch set will be carried over to the next major product release. For example the fixes in a patch set for version 10.00.00.55 are included in the base release of 10.01.00.72. When a new version is available, you can safely upgrade without fear of losing a fix from a patch in a previous version.
If you encounter the following error or anything similar, please ensure that all instances are the OpenFlows product are closed (including platforms: AutoCAD MicroStation and ArcMap) and try right clicking on the patch and choose "run as administrator". You may also want to try re-downloading the patch in case the download was not complete. Further, ensure that the product and version that you have installed matches that label of the patch that you are trying to run. If that does not help, try rebooting your computer. If the problem still occurs, try temporarily disabling your antivirus or anti-malware in case it is interfering.
"Error Occurred during copying files from extracted location to installed directory. Contact tech Support"
If the patch installer indicates that the access to the path for one of the files is denied, try checking the read only attribute of the file. Browse to the file location as seen in the patch installer, right click on the file, choose Properties, then ensure that "read only" is unchecked.
If all else fails, the patched files can be manually extracted from the patch executable file. Before doing this, please confirm that the patch's intended product and version matches the product and version you are trying to patch. The executable file can be opened with a compression utility such as 7Zip or Winrar. For example with 7Zip, right click on the .exe file, choose 7Zip > Open Archive. Inside you will find a zip file, which contains folders corresponding to the product names. The files in the root of the product name folder should be extracted to the root of the product's installation folder, and the files in the x64 subfolder should be extracted to the x64 subfolder within the product's installation folder.
If you're encountering a green Windows Defender dialog when trying to run the patch, indicating that the app is unrecognized - this is normal and you can dismiss it by choosing "More Info" and then "Run Anyway".
Antivirus or security software flags the patch as a virus or suspicious
This has been known to occur starting in January, 2019, due to more strict checking of some antivirus and security software. The cumulative patch set may be falsely flagged as potentially malicious, due to the methods it uses to check your version and install the patch. You may need to add an exception in your antivirus or security software. Bentley will investigate amendment to the patch set installer to change its methods so as not to be detected as a false-positive with security software.
