I am trying to build the wmibeats code in windows 7 with the following command

E:\Go\_Prj\src\[github.com](http://github.com)\eskibars\wmibeat\>go build

and I get this error

**#[github.com/eskibars/wmibeat/beater](http://github.com/eskibars/wmibeat/beater)**  
\*_beater\wmibeat.go:177: b.Events undefined (type beat.Beat has no field or method Events)_

When I try to run the command  
E:\Go\_Prj\src\[github.com](http://github.com)\eskibars\wmibeat\>make  
i get the following error

**glide update --no-recursive**  
**make: glide: Command not found**  
**make: \*\*\* [Makefile:14: init] Error 127**

I am very new to the go programming language and finding it difficult to debug it.  
Please guide  
Sunil

Ok, just figured it out. I had to download glide from [here](https://github.com/Masterminds/glide/releases/download/0.10.2/glide-0.10.2-windows-386.zip) and set it an the Path variable.  
That fixed it

Hi Sunil-

I have downloaded the Release file ([https://github.com/eskibars/wmibeat/releases](https://github.com/eskibars/wmibeat/releases)) of wmibeats and tried building it with the command (./wmibeat -c wmibeat.yml -e -d "\*") on my windows-7 machine.

But, I get this error message "Start error: loading config file error: Failed to apply config wmibeat.yml: type mismatch. Exiting."

The downloaded release version has only couple of files, wmibeat.exe and .yml files.

Please let me know, how do I resolve this issue. Thanks !

this error message seems to be related to your config file.

Thanks for your reply Steffens.  
I downloaded the wimbeat as a zip file from GIt repository; I've got only .exe and .yml files. I don't see any config files.  
Download Path: ([https://github.com/eskibars/wmibeat/releases](https://github.com/eskibars/wmibeat/releases))

I do not want to the build the project again, I was trying to download, configure it and run the service.

Could you please point me to the right path to download the full content of winbeat files. Thanks !

Prakash.

Can you post the full log file, please? I assume you didn't change anything in the yml file?

Hi,

I gave up when tried to rebuild it because I still had that issue after I completed implemeting for the client windows environment all the prerequired components git & goland & elastic beats & go-ole & glide.

C:\Go\src\[github.com](http://github.com)\eskibars\wmibeat\>go build

# [github.com/eskibars/wmibeat/beater](http://github.com/eskibars/wmibeat/beater)

beater\wmibeat.go:174: [b.Name](http://b.Name) undefined (type \*beat.Beat has no field or method Name)  
beater\wmibeat.go:177: b.Events undefined (type \*beat.Beat has no field or method Events)

so I took and used the relased build which contain the wmibeat.exe & wmibeat.yml, configued the executed it successfully (using wmibeat -c wmibeat.yml -e -d "\*")  
The only issues I had to figure out was for places at the yml config file where I used the TAB key - only regular spaces allowed.  
My sample configuration:

```
