Which flags are you passing to GACUTIL?

<div>
workingdir: C:\WINDOWS\Microsoft.NET\F<wbr />ramework\v<wbr />2.0.50727<br />
filename: gacutil<br />
Args: -if &quot;path to dll&quot;
</div>


workingdir: C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727
filename: gacutil
Args: -if "path to dll"

Sorry I meant this working directory on the client (.net 3.5 is required by the installer for the client application):<br />
C:\WINDOWS\Microsoft.NET\F<wbr />ramework\v<wbr />1.1.4322<br />
<br />
Also fyi, our DLL and application are both tageting .net 3.5<br />
<br />
Just using the &nbsp; <b>-if &nbsp;</b> flag

Following up incase others have this issue. We switched from using Process &gt;&nbsp;REGASM to using Assembly / RegistrationServices class. When users had .net 4 installed it was failing with REGASM. I think this is a better solution than running the command line tool.

How can we install a DLL into the GAC Assembly programatically through either a process or file action via visual studio VB 2008? We have tried many ways and need your help!<br />
<br />
The process runs on startup within a distributed windows forms application. We would like to overwrite the DLL if it already exists at this point.<br />
<br />
Basically the only way we get it to install is by dragging it into the windows assembly folder manually. The .NET gacutil on the clients results in &quot;Unknown Error&quot; always.

Register DLL in GAC Programatically

Visual Basic .NET (VB.NET) is an object-oriented programming language implemented on the .NET framework, but also supported on other platforms such as Mono and Silverlight. Microsoft launched VB.NET as the successor to the Visual Basic language. Though it is similar in syntax to  Visual Basic pre-2002, it is not the same technology,

Visual Basic.NET

An assembly language (or assembler language) is a low-level programming language for a computer or other programmable device in which there is a very strong (generally one-to-one) correspondence between the language and the architecture's machine code instructions. Each assembly language is specific to a particular computer architecture, in contrast to most high-level programming languages, which are generally portable across multiple architectures, but require interpreting or compiling. Assembly language is converted into executable machine code by a utility program referred to as an assembler; the conversion process is referred to as assembly, or assembling the code.

Microsoft Windows XP is the sixth release of the NT series of operating systems, and was the first to be marketed in a variety of editions: XP Home and XP Professional, designed for business and power users. The advanced features in XP Professional are generally disabled in Home Edition, but are there and can be activated. There were two 64-bit editions, an embedded edition and a tablet edition.
