I am using synonyms token filter with custom file

installed elasticsearch 6.7 as a service on windows 10 machine  
my "synonyms.txt" is located at "C:\ProgramData\Elastic\Elasticsearch\config\analysis\synonyms.txt"

here is my index settings

```
PUT /synonyms
{
"settings": {
"analysis": {
"filter": {
"synonym": {
"type": "synonym",
"synonyms_path": "analysis/synonyms.txt"
}
},
"analyzer": {
"my_analyzer": {
"tokenizer": "standard",
"filter": [
"lowercase",
"synonym"
]
}}
}
},
"mappings": {
"_doc": {
"properties": {
"description": {
"type": "text",
"analyzer": "my_analyzer"
}
}
}
}
}

```

i am getting this error while creating above index  
{  
"error": {  
"root\_cause": [  
{  
"type": "illegal\_argument\_exception",  
"reason": "IOException while reading synonyms\_path\_path: C:\ProgramData\Elastic\Elasticsearch\config\analysis\synonyms.txt"  
}  
],  
"type": "illegal\_argument\_exception",  
"reason": "IOException while reading synonyms\_path\_path: C:\ProgramData\Elastic\Elasticsearch\config\analysis\synonyms.txt",  
"caused\_by": {  
"type": "no\_such\_file\_exception",  
"reason": "C:\ProgramData\Elastic\Elasticsearch\config\analysis\synonyms.txt"  
}  
},  
"status": 400  
}

also tried synonyms token filter in elasticsearch installed as archive distribution (.zip) on windows machine but getting same error  
but in linux machine for both archive as well as package distributions it is working.

Thanks in advance.happy searching
