Unable to install dotTrace


Installing the Resharper Ultimate suite fails when it gets to dotTrace.

It's reporting that it can't find the package "EtwService.msi".

Hi David,

It looks like cached .msi file for our ETW Collector service was removed from Windows cache. Please download this tool from Microsoft: https://support.microsoft.com/en-us/help/17588/fix-problems-that-block-programs-from-being-installed-or-removed , run it, Select "Installing"/JetBrains ETW Host Service/"Yes, try uninstall".

Then you need to reinstall dotTrace or you can just open %localappdata%\JetBrains\Installations\dotTrace07\Msi.x64 folder, right-click on EtwService.msi file and select "Install" option.

I've tried using the desktop and the web installers.


That worked.  Thanks you.



I have the same problem with the last installer (2017.2)

I have used the MS tool but in the list the "JetBrains ETW Host Service" is missing!!!

In the services I have the "JetBrains ETW Collector 108.0.20170227.83302-eap03" service, also if I stop manually the service the installation fails.

If I try to reinstall the previous version (2017.1.3) all works fine, but I'm not able to upgrade on the last version.

Thanks for any support.

As last operation I have tried to delete manually the service but also in this case I'm not able to install correctly the EWT service


Additional information on my problem.

My user does not have the Administrator privileges, and I think this is the problem.

If I install the dotTrace by running the installation with and user with Administrator rights, the installation works fine and the EWT service is installed correctly, but if after I try to repair the installation on the normal user I have the same error message (also if the service is correctly installed with the previous installation).



Probably I found the solution.

In the registry, under the "HKEY_USERS\S-1-5-21-xxx-xxx\Software\Microsoft\Installer\Products\" was present the node "DD2EB8C7C5F7A9849B0984DC89239DE7" related the "JetBrains ETW Host Service" (old installation)

To allow the correct installation I have deleted this node (after a backup for security), repaired the installation, and now magically the installation is completed without any problem, also the ETW service!

After this new installation, under Products, I have the new node "E0B97671A860479438BCC6C355A63321" with the correct path to the MSI file.


I've just experienced a very similar issue which relates to the elevated permissions required in our company to install the DotTrace program in Resharper 2019.2.2

When you install the program as a normal user everything seems to be installed to C:\Users\user\AppData\Local\JetBrains\Installations\dotTrace192\Msi.x64\EtwService.msi but when you switch to the elevated user this folder is not accessible and the installer will not use a subst or network directory



I am having the same problem except that it happens after all 6 sub-products are shown as "Done"

Then it says "The older version of JetBrains ETW Host Service cannot be removed. Contact your technical support group."

I wonder if this web site is my technical support group.
