Gac Access Denied Error

SchioldanNovember 9, 20100 0 0 0 On a SharePoint 2010 remove assembly from gac access is denied development server running Windows Server 2008 R2, assembly cache viewer uninstall failed access is denied I had to uninstall some assemblies in the GAC and I kept windows assembly access is denied getting access denied, when trying to delete them. This was the case both using gacutil.exe and the Windows assembly could not be uninstalled because it is required Explorer when running in Administrative mode. So, looking for at a way to do this, I had to change a Local Security Policy, in order to allow them to be deleted: * Open Local Security Policy MMC
Local Security Policy Mmc
* Goto Security Settings -> Local Policies -> Security Options * Locate "User Account Control: Run all administrators in Admin Approval" and change the setting from Enabled to Disabled * Reboot and now the assemblies can be deleted IMPORTANT! Never ever do this on a production system, and always turn it back on afterwards.

Uninstall From Gac
supposed to post this issue few months ago, but I don't really gacutil.exe location know why this has been in my draft folder till this date! When we were migrating our install gacutil servers to new environment, we deployed some custom web parts manually. While deploying the web part (Drag and drop the assembly (web part .dll) into Global Assembly Cache (GAC) folder) I have got https://blogs.msdn.microsoft.com/mortens/2010/11/09/access-denied-trying-to-uninstall-assemblies-from-gac/ the following wired error message!😦 GAC normally located in C:\Windows\assembly directory, and ‘WebPartStepBiStep.dll‘ is my web part assembly. After spending some time on the web, I have got the solution here. Actually the ‘User Account Control: run all administrators in Admin Approval Mode' was Enabled on the Local Security Policy. Which means the local administrators group required Admin Approval https://stepbistep.net/2012/06/26/access-is-denied-xxx-dll-manually-add-an-assembly-dll-to-the-gac-on-windows-server-2008-r2/ Mode (AAM) to perform these kind of operations. Here is the definition for Admin Approval Mode (AAM) from MicroSoft site. Admin Approval Mode: AAM is a User Account Control (UAC) configuration in which a split user access token is created for an administrator. When an administrator logs on to a Windows Server 2008, the administrator is assigned two separate access tokens. Without AAM, an administrator account receives only one access token, which grants that administrator access to all Windows resources. To access the Local Security Policy, either we can goto the Administrative Tools -> Local Security Policy OR we can run the ‘secpol.msc' on the command prompt. Start -> Administrative Tools -> Local Security Policy Click Start -> Cmd -> type ‘secpol.msc' then enter You will be getting the Local Security Policy window like below and the highlighted is the AAM. So the solution for our problem is Disabled the User Account Control. To do this double click on the highlighted policy on the Local Security Policy above and then you will be getting this window. Click Disabled and OK. After disabl

As suggested in the answers to that question, you need Gacutil.exe to do this, or preferably an install program. –Cody Gray Feb 28 '11 at 10:43 As everybody else has suggested, use GacUtil. –Pradeep Feb 28 '11 at 11:04 This is a common issue that a lot of developers have run into (that isn't necessarily fixed by disabling UAC). It is also the top google hit for this issue. I really am getting sick of people closing every question they don't personally find useful on this site. The vista answer linked as a duplicate does not work for this case. –Kelly Gendron Nov 2 '15 at 18:21 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote Have you tried starting Windows Explorer as Administrator? Even if your user account has admin rights you still need that elevation for such tasks. If this doesn't work, I suggest you use gacutil.exe. You also have to open the command prompt as administrator then: In start menu find the link to the command prompt of your visual studio installation. If this isn't your development machine you need the SDK or just copy gacutil.exe. Right clic
