Before anything else, try to restart the R session:
* In R studio, on top go to "Session"
* "Restart R"

## Can not install the package

Note that in case you get the following error:

```
InternetOpenUrl failed: 'An error occurred in the secure channel support'
``` 

Enter the command:

```
setInternet2(TRUE)
```

Alternatively, you may add to .Rprofile or Rprofile.site the following line:

```
options(download.file.method = "wininet")
```

## Unable to move temporary installation

One common errors during the package installation is linked to the antivirus _"real time file system protection"_. The following will fix the problem:

```
trace(utils:::unpackPkgZip, edit=TRUE)
```
Edit line 140:

```
Sys.sleep(0.5)
```
to:

```
Sys.sleep(2)
```

## Error in strptime(xx, f, tz = tz) :  unable to identify current timezone 'C':    please set environment variable 'TZ'

```
## enter this commaned to set up the time zone - you may change it to another anotherone.
Sys.setenv(TZ='GMT')
## Now you can check...
Sys.timezone()
Sys.getenv("TZ")
```

 


## Error when building the dictionnary or configuration file

If you see this message (or similar error):
```
Error in file(file, ifelse(append, "a", "w")) : 
  cannot open the connection
```
It is most likely because you have the form, dictionary or data set open in excel on your computer. Only a single session for that file is allowed in windos. If you close it and start over, the problem should be fixed.
