    I'm also experiencing an issues trying to install the current version of URL ReWrite

    I've tried installing via Web Platform Installer and via downloading the x64 version of MSI but get an error when trying to install on Windows Server 2016.

    I'm running Build 14393.2485 if that's on any relevance.

    Looking at the digital signature on the MSI it appears a new version was released on September 12th 2018 as that is when this release was timestamped, so it appears the issue seems to be specific to this updated release.

    I can't seem to find a download any way to download the June 2017 release as all the links download the current release.

    Hello Sujith Tummala,

    I could reproduce the issue like you.

    After I comparing the installer file I download last month and the installer I donwload today, I think URL rewrite team maybe updated the download file incorrectly.

    For current workaround, I will upload the isntaller file I download last month, you could try to get it from


    We will continue focus on the issue. If it is fixed, we will inform you.

    Best Regards,

    Thanks for posting a link to a copy of the June 2017 installer.

    That installer worked for me.

    Hi Terry

    I just wanted to extend my thanks to you too.

    I had encountered exactly the same issue as Les, but the previous version you kindly posted above worked <g class="gr_ gr_84 gr-alert gr_gramm gr_inline_cards gr_run_anim Grammar only-ins replaceWithoutSep" id="84" data-gr-id="84">first</g> time.

    Think some improved testing might be needed before the next release!

    Kind regards

    Hello Terry,

    Do you have some news about this issue?

    Same issue here. We are using the following link:


    Log:Starting Installation
    Started downloading products...
    Started downloading: 'URL Rewrite 2.1'
    Downloaded: 'URL Rewrite 2.1'
    Install completed (Failure): 'URL Rewrite 2.1'
    UrlRewrite2 : Failed.
    Downloaded file failed signature verification and may have been tampered with

    Does anyone have the previous version of this available? Is there any way to flag this with Microsoft to get an ETA on the official links being fixed?

    Hi Ian,

    Apologies probably wasn't clear from the post, I have already tried it but it failed in our build still. My understanding is this is because its a different file that is being downloaded.

    Terry was using: rewrite_amd64_en-US.msi

    Our build is using: WebPlatformInstaller_amd64_en-US.msi

    I'm currently trying to get access to current live servers to get the old version of this file off them, upload it and download as part of our build from the new location. Was just hoping someone could possibly link it to me in here quicker than I can do this :)

    Think I've sussed it out, our build does a powershell install of the WebPlatformInstaller, which reaches out to download the Url Rewrite module and presumably gets the latest version. I will start working on editing the powershell to download just Terry's file - just need to figure out the powershell for a quiet install and accept agreements and mod those lines too.

    Hi Andrew

    The MSI you mention is actually the setup package for the Web Platform Installer itself and doesn't include the URL Rewrite installer within that. You would install the WPI first and then use that to install the URL rewrite package.

    You can download the latest WPI setup package from here: https://go.microsoft.com/fwlink/?LinkId=287166 (x64 version)

    Having built a new server three days ago, I know the latest WPI setup package to be working, but then encountered the URL rewrite issue discussed above. The error messages you posted list the same error regarding the URL rewrite package, there is no mention of an issue with the WPI package.

    I would recommend downloading the latest WPI package and combining that in your build with the URL rewrite package kindly provided by Terry above as this has resolved the issue for both me and others in this post.

    Kind regards

    And you'd already come to a similar conclusion, excellent news!

    Hmm, I use chocolatey to provision my servers and they are failing on the same thing. Hope this is fixed at source soon!

    Is there any way to perform a headless install of the link by Terry? Our scenario is we are creating a base image (via Packer) which is used in an auto scaling group on AWS. A manual install is not an option, copies will be rolled up and torn down as needed. All releases to our dev environment are blocked by this issue, and thus no updates can go out to staging or production either.

    What we used to do (and hopefully can get back to doing):

    Invoke-WebRequest 'http://download.microsoft.com/download/C/F/F/CFF3A0B8-99D4-41A2-AE1A-496C08BEB904/WebPlatformInstaller_amd64_en-US.msi' -OutFile c:/msi/WebPlatformInstaller_amd64_en-US.msi

    Start-Process 'c:/msi/WebPlatformInstaller_amd64_en-US.msi' '/qn' -PassThru | Wait-Process

    Set-Location 'C:/Program Files/Microsoft/Web Platform Installer'; .\WebpiCmd.exe /Install /Products:'UrlRewrite2' /AcceptEULA /Log:c:/msi/WebpiCmd.log

    I have currently copied Terry's link, added it to an S3 location to be put on the disk at image creation time. However, I cannot get a headless install to work with:

    Start-process msiexec.exe -Wait -ArgumentList "/i C:/msi/rewrite_amd64_en-US.msi /qn /passive /L*V `"C:/msi/log.txt`""

    So I am currently digging into the documentation at:


    I am going to attempt creating an offline cache, then hopefully overwrite the offline Url Rewrite file with Terry's, then attempt an offline install. Sound like an idea? No idea if it will be that simple - hasn't been so far!

    This should be resolved now.. it's been rolled back and now  just CDNs need to reflect this change (roll-back)...

    Can you post the download URL for the English x64 MSI so we are certain we are attempting the correct URL?

  • User-1084200161 posted

    sorry, just got an update that it's still being actively worked on..  looks like there's a bit of a delay in getting the updated (rolled back installer) up on the download center..

    EDIT: I just tried on two different machines and it worked on both (they were on different networks).. downloading from:


    install was successful.

    Noah, can you try again?

    I can confirm it works fine for me now. Thanks for sorting it out so quickly :)

    Could anybody please provide URLs for the updated localized versions? At least the de_DE version is f*cked up as well

    EDIT: Seems like installing the en_US version apparently still leads to localized installs. So using the en_US works, but is counterintuitive. But the WebPlatform Installer still fails on de_DE

    The Japanese x64 link is still wrong.

    Please correct the links of the localized versions too.
